In MATLAB, "linear filtering" is a technique used to apply a linear filter to a digital image. The fundamental principle behind the working of linear filtering is convolution. This article is meant for explaining the concept of linear filtering and how to perform linear filtering without using the "imfilter" function in MATLAB. What is Linear Filtering? In digital image processing, the process of applying a linear filter (also called convolution kernel) to a digital image is called linear filtering. The working of linear filtering is based on the concept of convolution. In the process of linear filtering, a convolution ... Read More
MATLAB provides various built-in functions to reverse a string of text. In this tutorial, I am going to explain all the commonly used methods to reverse a string in MATLAB. Reverse a String Using "reverse" Function in MATLAB There is a built-in function "reverse" in MATLAB that we can use to reverse a string. Syntax reversed_string = reverse(string); The steps involved in reversing a string using the "reverse" function are given below − Step (1) − Create a string of text. Step (2) − Call the "reverse" function to reverse the string. Step (3) − Display the ... Read More
In MATLAB, there are various methods and functions for reversing a given number. In this tutorial, I will explain all these methods one-by-one with the help of examples. Reverse a Number Using "fliplr" Function in MATLAB The "fliplr" is a built-in function in MATLAB that we can use to reverse a given number. Syntax reversed_num = fliplr(number); Here, the "number" must be a string. Here are the steps involved in reversing a given number using the "fliplr" function in MATLAB. Step (1) − Input the number. Step (2) − Convert the input number to a string. For ... Read More
MATLAB provides various methods and functions to remove spaces in a string. In this tutorial, we will cover the commonly used methods for removing extra spaces in a string. So, let’s start. Remove White Space in a String Using "isspace" Function In MATLAB, the "isspace" function is a built-in function that is used to determine and remove the ASCII white space present in a string. Syntax string_without_space = isspace('input_string'); Example Let us take an example in MATLAB programming to use this function to remove white spaces in a string. % MATLAB code to remove white space from ...

Powerful spreadsheet software like Excel provides a variety of features to alter and analyse data. Finding the number of distinct values in a filtered column is a typical task that can be helpful when working with huge datasets. Excel data filtering enables you to focus on particular subsets of your data by only displaying rows that match specified criteria. The ordinary COUNT function, however, merely counts the visible cells, including any duplicates, when a column is filtered. We need to use a different strategy in order to precisely count the unique values in a filtered column. In this article, we'll ... Read More

There are multiple ways to clear/empty an array in JavaScript. You need to use them based on the context. Let us look at each of them. Assume we have an array defined as − let arr = [1, 'test', {}, 123.43]; Substituting with a new array − arr = []; This is the fastest way. This will set arr to a new array. This is perfect if you don't have any references from other places to the original arr. If you do, those references won't be updated and those places will continue to use the old array. Setting length prop ... Read More
The Hashmap is the one kind of data structure that stores the key-value pairs of the different data. Like other programming languages, TypeScript also contains a built-in map data structure. In JavaScript, we can't define the key or value type that needs to be stored in the map. So, we need to create a map of the generic type. In TypeScript, we can define the type of the key and value to be stored in the map. Syntax Following is the syntax create the map in TypeScript − let hashMap = new Map(); Parameters key_Type − It is ... Read More
