Introduction to Matlab xticks

The ‘xticks function’ is used in Matlab to assign tick values & labels to the x-axis of a graph or plot. By default, Matlab’s plot function (used to draw any plot) creates ticks as per the default scale, but we might need to have ticks based on our requirements. Adding ticks per our need and labelling them make the plots more intuitive and easier to understand. For this, we can use the xticks function along with the xticklabels function in Matlab to easily identify the values of our choice on the plots.

xticks (A) xticks (A : B : C)

Explanation:

You use xticks(A) to set the ticks defined by the vector A. Please note that A must have values in ascending order.

You use xticks(A: B: C) to set the ticks defined by the range A to C with a gap of B between the ticks.

Examples of Matlab xticks

Given below are the examples of Matlab xticks:

Example #1

In this example, we will use the plot function to plot a sine wave and then set the ticks for it using the xticks function.

Below are the steps to be followed:

Write the code to create a sine wave.

Use the xticks function to set the ticks for the x-axis.

Use the xticklabels function to set the labels for the ticks defined in the above step.

Code:

[Initializing the range for sine wave] [Initializing the sine wave] [Using the plot function to plot the sine wave] [Using the xticks function to set the ticks for the x-axis] [Using the xticklabels function to set the labels for the ticks]

Input:

Output:

As we can see in the output, we have obtained ticks of our choice, i.e., 0, 3, 6, using the xticks function. We have also set the labels for these ticks using the xticklabels function.

Example #2

In this example, we will use the plot function to plot a cos wave and then set the ticks for it using the xticks function.

Below are the steps to be followed:

Write the code to create a cos wave.

Use the xticks function to set the ticks for the x-axis.

Use the xticklabels function to set the labels for the ticks defined in the above step.

[Initializing the range for cos wave] [Initializing the cos wave] [Using the plot function to plot the cos wave] [Using the xticks function to set the ticks for the x-axis] [Using the xticklabels function to set the labels for the ticks]

Input:

Output:

As we can see in the output, we have obtained ticks of our choice, i.e., 0, 3, 6, 9, using the xticks function. We have also set the labels for these ticks using the xticklabels function.

In the above 2 examples, we have passed all the values we want to set as plot ticks as arguments to the xticks function.

Next, we will see how to set a range of values with a fixed interval as the ticks of a plot.

Example #3

Below are the steps to be followed:

Write the code to create a sine wave.

Use the xticks function to set the ticks for the x-axis.

Use the xticklabels function to set the labels for the ticks defined in the above step.

Code:

[Initializing the range for sine wave] [Initializing the sine wave] [Using the plot function to plot the sine wave] [Using the xticks function to set the ticks for the x-axis]

Input:

Output:

As we can see in the output, we have obtained ticks of our choice by passing a range as an argument to the xticks function.

Conclusion

The xticks function is used in Matlab to assign tick values to the x-axis. The xticklabels function can be used along with the xticks function to label the ticks assigned. A range and a set of values can be passed as an argument to the xticks function.

What Is The Use Of Flag In Matlab Coding?(Examples)

Introduction to Matlab Flag

Flag is a variable that we use as an indication or a signal to inform our program that a specific condition is met; mostly it is a Boolean variable (taking two values: True or False). For example, if we want all the element of an array to be even, then a Flag variable can be set, and it will become False whenever any value in the input array is odd.

Syntax:

Start Your Free Data Science Course

Hadoop, Data Science, Statistics & others

Flag = True

Description:

Flag can be returned as an output of a function or method

It can also be used as a condition to perform a specific task. The task will be performed continuously if the Flag is True and will stop once the Flag turns to False

Set Flag in Matlab with Different Examples Example #1

Let us start with a very basic example of using a Flag variable to control a while loop. For this example, we will follow the following steps:

Set Flag variable equal to True

Start the while loop with the condition that Flag should be True

Use the While loop to display a message

Set the Flag to False to ensure that loop does not work indefinitely

Syntax:

flag = true

[Initializing the Flag to True]

while flag == true

[This while loop will be executed only if flag is equal to True]

flag=0;

[Setting the Flag again to ‘0’ (logical False) so that the loop does not work indefinitely]

disp(‘Let us learn Flag in MATLAB’);

[Displaying the test output]

end

[Please note that, the while loop will get terminated here as we have set the Flag to False inside the while loop]

Code:

end

Output:

As we can see in the output, we have obtained our text output displayed once, as expected by us.

Example #2

In this example, we will write code for a command which will be executed continuously after a fixed interval. For this example, we will follow the following steps:

Call the timer function: Our aim is to create a timer that displays seconds continuously until the Flag variable turns from True to False.

Set the Flag to True initially.

Set the Flag to False in the while loop whenever we want the timer to stop.

Set the Flag to True, to start the timer all over again.

Syntax:

‘StartDelay’, 5);

[Initializing the Timer and setting the FLAG as False. This timer will work only when the Flag is turned to True]

start (timerFunction)

[Calling the start function to execute the timer]

[Setting the Flag variable to True]

startingTime = 1;

[Initializing the point from where timer will start]

while (Flag = = true)

[Using the while loop to check over the Flag every time a second is displayed] [Please note that this loop will be executed only if the Flag is True] pause (1)

[This will set the interval time between every output] end

[1st task will end here] ‘StartDelay’, 7);

[The Flag is again set to False inside the timer] Flag=true;

[The flag is turned back to True and the entire process will repeat itself] end

Code:

end

Output:

As we can see in the output, we have obtained the timer outputs corresponding to the 3 tasks. The outputs here are controlled using the Flag variable. When implemented in a live editor, every output digit will be displayed at an interval of 1 second.

Example #3

Set Flag to True

Run the while loop

Set the Flag to False once we have values till 100

Syntax:

Flag = true;

[Initializing the Flag and setting it to True]

while Flag == true

[Setting the condition to ensure that the loop runs only as long as the Flag is True]

x = 50 :2 :90;

[Defining the range to be displayed]

Flag = false;

[Setting the Flag to False once all the numbers are displayed]

end

Code:

end

Output:

As we can see in the output, we have obtained alternate numbers between 50 to 90 using a while loop which is controlled by the Flag variable.

Working And Examples Of React Format

Introduction to React Format

Displaying a number on a webpage or an application is an easier task, but when it comes to formatting it, it becomes hectic. This hectic work has been simplified in this article. The format is the best way to represent a number so that it can have some meaning and provide more information to the user. By using appropriate formatting, we can enhance the readability and usability of numeric data. The article’s objective is to illustrate different approaches for formatting numbers to convey their intended meaning effectively. The examples would represent the concept more simply for the reader so that they can apply the same in their work.

Number Format Syntax

import NumberFormat from 'react-number-format'

Currency Format Syntax

import MaskedInput from 'react-text-mask' Working of React Format

The above syntaxes can convert numerical digits into numbers or a currency format. The library “NumberFormat” can be imported for formatting the digits into a meaningful numbers, and MaskedInput can be used for currency formatting.

Examples

Lets us discuss the examples:

Example #1 – Basic

In the example below, we have used ‘react-number-format’ to import the Number format in the code. A basic example of a Number Format is displayed below.

The files used in the example are:

[i] index.js

import React , {Component} from 'react' import {render} from 'react-dom' import NumberFormat from 'react-number-format' import AutosizeInput from 'react-input-autosize' export class App extends Component { state = {n: '0'} render() { return ( <NumberFormat customInput={AutosizeInput} isNumericString={true} allowNegative={false} decimalSeparator="." decimalScale={3} value={this.state.n} ) } }

Output:

Example #2 – Advance

For implementing the code, the files used are:

[i] reactSelectOptions.js

export default [ { value: "data analysis" , label: "Data Analysis" }, { value: "data engineering" , label: "Data Engineering" }, { value: "data science" , label: "Data Science" } ];

Discord Markdown Syntax And Text Formatting: Complete Guide

4.6K

Formatting text adds a flavor to the message we send on Discord. Markdown syntax makes the message look cool and helps it stand out in a sea of text. All of this is possible because of the Discord Markdown language. Here’s how it works. Simply send the message with a few special characters (markdown language) before and after the text to format it. You can use it to make the text bold, underline, strikethrough, code block, or even add a spoiler tag. You can also combine two formatting options like striking through a bolded text. Here’s all the formatting syntax you need to know to make your message read better on Discord.

Discord Markdown Syntax and Text Formatting

Let’s start with the basics.

1. Bold Text

To make the text bold, just add two asterisks(**) before and after the message that you are sending. Here’s an example.

**This will make the entire text bold on Discord**

You can also choose to make only a certain part of the message stand out.

This will only **Bold** part of the message. 2. Italic Text

Instead of using two, just use one asterisk (*) before and after the text to make it Italic. You can also choose to only highlight a specific part of the message just like in bold.

*This will make the text italic on Discord* 3. Underlining Text

Underlining text in the chat makes it easy to find important stuff in long messages. This can come in handy at times. On Discord, you can use two underscores (__) before and after the text to underline.

This is something __important__ 4. Strikethrough Text

Strikethrough is one of the most commonly used text formatting options in chats. It can be used to point out mistakes or to highlight, say, change in the price. To strike through, use two tildes (~~) before and after the text.

This is how you can ~~underline~~ Strikethrough text on Discord. 5. Code Block

Discord also supports its own code block. Wrap the text in the backtick (`). Similar to other formatting options, you can also use this in the middle of the sentence.

On Discord, this is just going to add a black box around the text to make it stand out.

`printf("This is going to be in code block");` 6. Multiline Code Block

Discord supports two types of code blocks. While the previous code block only added a black box around the text, the multiline code block will place the code in a bigger box, changes the font style, but cannot be placed in the middle of the sentence. This is a code block that we normally use in many other services.

To use a multiline code block, add three backticks (“`) before and after the text to make it a code.

``` printf("This is a bigger multiline code block"); exit ```

To make the text green, use backticks and diff just like in the case of red. But use this plus (+) symbol before the message like this.

```diff +go green ```

For Blue, use ini syntax after the backticks and wrap the text in square brackets.

```ini [now it's blue time] ```

Use ini syntax and hashtag (#) before the text to chat in gray. Use css syntax and wrap it up in square brackets ([]) for orange. Fix syntax without any character before the text to get yellow.

11. Changing the Font

There isn’t any in-built way to change the font on Discord. But you have a small workaround that is fairly easy to use. There are a plethora of Discord font generators like Lingojam and Bigbangram. You can use such tools to change the font.

Just enter the message on those sites. They will show you the same message in different fonts. Copy the one you like and paste it in Discord chat to send it.

12. Using Multiple Formatting Commands

You can actually combine more than one syntax together. For example, you can strike through the bold text like this.

~~**Striking bold text**~~

Similarly, you can combine as many syntaxes as you can. Make it bold, italic, and underline at the same time. Change the font, color and send it as a spoiler, etc.

Wrapping Up – Discord Text Formatting

You can use some formats without using commands in Discord. Just enter the message and select the text you want to format. This will open a pop-up menu with options to make the text bold, italic, strikethrough, blockquote, code block, and even make it a spoiler. Anyhow, these Discord shortcuts will just add markdown syntax to the message automatically.

Working Of Methods Inwith Examples

Introduction to chúng tôi Methods

Vue.js methods are defined as a function to perform certain actions whenever the user is needed and the method is associated with a Vue instance as the method is similar to function like in other programming languages. In chúng tôi methods are defined using the “method” name property before declaring or using it as a method in the chúng tôi app code, in simple words we can say methods are function associated with an instance which are defined inside the method property, methods are usually defined similarly to as declaring “def” in the python for defining methods or functions and in chúng tôi we use “method” property.

Working of Methods in chúng tôi with Examples

Here, we will discuss the method declaration in chúng tôi In this, methods are defined or declared inside the method property which means we have to write “method” before writing the method body. In chúng tôi methods are useful for connecting functionality to directives for handling the events. This can also be said to define any piece or small code of logic we need to use methods and this logic can be used for any other function or in the rest of the program. So we can also call a method inside a lifecycle hook also which is also another way of using methods in Vue.js.

Let us demonstrate how to declare methods in chúng tôi with the below syntax and example.

Syntax:

new Vue({ e1: '#app' ……. methods: { piece of code or logic } )}

In the above, we can see the syntax for declaring methods in the chúng tôi code snippets. In this, we can see we have declared method property to define or declare methods that will have a piece of code or logic within the method property which we want it to call in another method or rest.

Example #1

So let us consider a simple example for demonstrating the use and declaration of methods in Vue.js.

Html File:

Vue js App Code:

new Vue({ el: '#app', data: { message: 'information' }, methods: { func() { this.message = 'Educba Training Institute'; } } });

Output:

Now we know whenever we need some actions or events to be performed then these methods are the easiest and useful ways to use in such cases. To do this a venue provides a directive called v-on which can be used to handle the events.

In chúng tôi accessing the date or message from the method is also simple as we saw in the above program where data to be accessed it written as the value of “message” which is information and this is accessed inside the method using “this. message” whereas we don’t need to use “this.data. message” which would rather throw an error and hence chúng tôi provides transparent binding with the use of method property. And in the above program, we also saw they are closely interlinked to the events and hence in chúng tôi the methods are mostly used as event handlers.

In chúng tôi methods are also used to handle inline js statements because where instead of binding to the method name we can use inline statements using methods.

Example #2

Html file:

Vue js Code:

new Vue({ el: '#methodapp', methods: { disp: function (info) { alert(info) } } })

Output:

Conclusion

In this article, we conclude that the concept of the method in chúng tôi is similar to that of functions concepts in other programming languages. In this article, we saw how to declare methods using “method” property before writing the function logic code and we also saw how we have used methods as an event handler using v-on directive along with which we also saw how it used for binding inline javascript statements instead of directly binding with the method names.

Top Examples Of Scala Collections

Introduction to Scala Collections

Collections in Scala are nothing but a container where the list of data items can be placed and processed together within the memory. It consists of both mutable (scala.collection.mutable) and immutable (scala.collection.immutable) collections which in-turn varies functionally with Val and Var and also, Scala collections provide a wide range of flexible built-in methods, which can be used to perform various operations like transformations & actions, directly on the data items.

Web development, programming languages, Software testing & others

Scala Collections Framework

At a very high-level collection contains Seq, Set & Map. All of them are the child of Traversable traits. Do keep it in mind, All of the Childs of Traversable (Parent) are Traits and not classes which makes it easier to implement in the code snippet, without having the need to create the object before calling it.

Let us discuss it in detail as follows:

Reference – Book: A Beginner’s Guide to Scala, Object Orientation and Functional Programming

Traversable: helps us to traverse through the entire collection and it implements the behavior that are common to all the collections irrespective of the data types. It simply means Traversable lets us traverse the collections repeatedly in terms of for each method.

Iterable: gives us an iterator, which lets you loop through a collection’s elements one at a time.

Note: By using an iterator, the collection can be traversed only once, because each element is consumed during the iteration process.

Mutable & Immutable Collections

Scala Provides 2 varieties of collections. They are:

Mutable

Immutable

Mutable Collections

Example:

AnyRefMap

ArrayBuffer

ArrayBuilder

ArraySeq

ArrayStack

BitSet

DoubleLinkedList

HashMap

HashSet

LinkedHashMap

LinkedHashSet

LinkedList

Stack

StringBuilder

TreeSet

WeekHashMap, etc.

Immutable Collections

This type of collection can never be changed. We can still see the methods that look like adding/ updating/ removing elements from the collection. But it actually creates a new collection internally and leaves the old one unchanged.

Example:

BitSet

HashMap

HashSet

List

ListMap

ListSet

LongMap

NumericRange

Stack

Stream

StreamIterator

TreeMap

TreeSet

Vector

IndexedSeq, etc..

String & Lazy Collection

Whenever we perform any data transformations using a filter, map, min, max, reduce, fold, etc.., on collections, it basically transforms it into another collection. There could be some collections that allow Strict Transformations means, the memory of the elements are allocated immediately when the elements are evaluated and results in the new collection. In a Lazy Collection, the transformations will not create another collection upfront. It means, the memory will not be allocated immediately and it creates the new collection when there is a demand. Collection classes can be converted into Lazy Collection by creating a view on the collection.

Let us look into the Scala REPL example for a better understanding.

Example:

Code:

object Demo { def main(args: Array[String]) { val ls = (0 to 5).toList println("List is: " + ls); } }

Output:

While creating the collection – List, the memory is allocated immediately and when we try to call the list, we are able to find the list of elements as below.

ls res0: List[Int] = List(0, 1, 2, 3, 4, 5) //collection items of ls is allocated to res0. Hence, it created the memory immediately.

To Create a Lazy Collection:

object Demo { def main(args: Array[String]) { val ls = (0 to 5).toList val lsLazy = ls.view println("View: " + lsLazy); } }

lsLazy: scala.collection.SeqView[Int] = View(?)

Note: Here when we try to create a view on the existing list, we can clearly say it doesn’t allocate the memory as it only builds a view of the list until unless any action is being called like foreach, min, max, etc.

Code:

object Demo { def main(args: Array[String]) { val ls = (0 to 5).toList val lsLazy = ls.view println("max "+lsLazy.max); } }

object Demo { def main(args: Array[String]) { val ls = (0 to 5).toList val lsLazy = ls.view lsLazy.foreach(println) } }

Let us investigate some of the basic methods that come with the Collections:

Mutable Collections: ArrayBuffer

Example:

object Demo { def main(args: Array[String]) { val arrBuff = (0 to 5).toBuffer println(" "+arrBuff); } }

Output:

Now, let’s try adding an element to the existing ArrayBuffer Collection.

object Demo { def main(args: Array[String]) { val arrBuff = (0 to 5).toBuffer arrBuff += 5 println(" "+arrBuff); } }

Look at the below result, if you look closer, you could find that data item “5” has been appended to the existing collection.

Note: += is a method that is used to append the element to the original collection. i.e., adds the new element to the collection and reassigns the result to the original collection.

Example:

Code:

object Demo { def main(args: Array[String]) { val arrBuff1 = (0 to 5).toBuffer println(" "+arrBuff1); } }

Output:

Code:

object Demo { def main(args: Array[String]) { val arrBuff1 = (0 to 5).toBuffer arrBuff1 +=66 println(" "+arrBuff1); } }

Output:

res24: scala.collection.mutable.Buffer[Int] = ArrayBuffer(0, 1, 2, 3, 4, 5, 66) // added in the copy, not the original

res25: scala.collection.mutable.Buffer[Int] = ArrayBuffer(0, 1, 2, 3, 4, 5) // check the original collection and note that the collection items remain unchanged.

Immutable Collection: List

Code:

object Demo { def main(args: Array[String]) { val ls = (1 to 5).toList println(" "+ls); } }

Note: Mutable collections doesn’t have += method to append and reassign.

object Demo { def main(args: Array[String]) { val ls = (1 to 5).toList ls :+5 println(" "+ls); } }

Note: Use ” :+= ” as the reassignment operator, while dealing with immutable collections to update the existing immutable collection. This method can be applied only on “var” and not on “val”.

Example:

Code:

object Demo { def main(args: Array[String]) { val ls = (1 to 5).toList } }

Output:

Note: map will always return the output of the same incoming data type. In the above screenshot, the input was List[Int], hence the output is also same. It output stored in “res13”.

Example:

Code:

object Demo { def main(args: Array[String]) { val ls = (1 to 5).toList ls.foreach(println) }

Output:

Note: If you look carefully in the screenshot, you can notice that the output of foreach hasn’t stored on any result variables here. This is why foreach varies with map.

Conclusion

As we have seen so far, collections are way useful to store and retrieve formatted items of the respective data types.
