As we know, MATLAB is a powerful tool to perform various operations on matrices and arrays. Vector is a type of matrix having only one row or one column. We can determine the inverted version of a vector using MATLAB. For this, MATLAB provides different methods and functions. So, let’s discuss the process of inverting a vector using different methods in MATLAB. Inverse a Vector Using Indexing Method in MATLAB In MATLAB, we can utilize the indexing method to find inverse of a given vector. In this method, the elements of the vector are arranged in the reverse order using ... Read More

CSV or Comma Separated Values is a file format that can store numeric and text values. The most important characteristic of a CSV file is that it allows to exchange the data among a variety of sources. MATLAB is a powerful tool that provides a large number of built-in functions to perform various operations. It provides the following two functions that enable the users to import data with numeric and text values from a CSV file into the MATLAB workspace. readtable() importdata() In this tutorial, I will show you the process of importing data from a CSV file ...

These three types of signals (unit step, sinusoidal, and exponential) are basic signals used in analyzing different types of systems. A unit step signal has a step of magnitude one after a specific time instant. A sinusoidal signal is a type of signal which has either a sine or cosine waveform. A exponential signal is a type of signal that rises or decays exponentially with time. We can use MATLAB to generate all these types of signals. In this tutorial, I am going to explain how you can generate unit step, sinusoidal, and exponential signal in ... Read More

A periodic sequence is one which repeats its pattern at regular intervals, whereas an aperiodic sequence is another type of sequence in which there is no regularity in the pattern. We can use MATLAB to generate periodic and aperiodic sequences. Before going to learn about generating periodic and aperiodic sequences using MATLAB, let us first get a brief overview of periodic and aperiodic sequences individually. What is a Periodic Sequence? A sequency of data points which has a regular pattern that repeats itself at a certain interval is called a periodic sequence. The interval over which the pattern of the ... Read More

FM stands for Frequency Modulation, a technique used in communication systems for long distance transmission of data and information. The frequency modulation involves the alteration in the frequency of the signal so that it can be transmitted over long distances without any distortion of the information. In this tutorial, I am going to explain how to generate narrowband and wideband FM signal using MATLAB. Before going to learn about generating narrowband and wideband FM signals, let us first get an overview of FM signal and its types. What is an FM Signal? An FM signal is a modulated signal which ...

As we know, MATLAB is a powerful tool that can be used to perform various operations on matrices. One such operation is finding the percentage of similarity between two matrices. Finding percentage of similarity between two matrices is crucial in various application such as digital image processing, data analysis, machine learning, and more. This tutorial will help you understand the step-by-step process of finding the percentage of similarity between two matrices using MATLAB. What is Percentage of Similarity Between Two Matrices? The measure that shows how closely two matrices are related in some aspect is called "similarity between two matrices". ... Read More

In a binary image, the interior and exterior skeletons are used to represent the essential structure of the objects and shaped within the image. In this article, I am going explain the process of finding the interior and exterior skeleton of binary image using MATLAB. Before discussing the process of finding the interior and exterior skeletons of a binary image. let us first get an overview of these two types of skeletons. What is the Interior Skeleton of Binary Image? In a binary image, the "interior skeleton" represents the centerline of the foreground objects. It is basically a thin representation ... Read More

We can use MATLAB to create a partially colored gray image, which we will discuss in this tutorial. But before that, let us first get an overview of what a partially colored gray image is used for. What is a Partially Colored Gray Image? A digital image in which some parts or objects are colored while the rest parts are in gray scale is called a partially colored gray image. In simple terms, a digital image which combines both color and gray scale objects in a single image area is called a partially colored gray image. Partially colored gray images ... Read More

In digital image processing, histogram equalization is a common method of improving the visual quality of a digital image. We can perform histogram equalization of a digital image using MATLAB. We have a built-in function "histeq" in MATLAB to perform this task. However, we can also perform histogram equalization without using the MATLAB’s "histeq" function. In this tutorial, I will show you the process of histogram equalization without using "histeq" function in MATLAB. But before that let’s get an overview of histogram and histogram equalization in digital image processing. What is a Histogram and Histogram Equalization? In digital image processing, ... Read More

In interpolation, filtering after upsampling is an important step to avoid the aliasing and reconstruction of a filtered signal. In MATLAB, there are various built-in functions that can be used to perform filtering after upsampling in interpolation. Before discussing the process of filtering after upsampling, let us first know about filtering and upsampling in interpolation. What are Upsampling and Filtering in Interpolation? In interpolation, upsampling and filtering are two crucial processes used to increase the number of samples in a signal. Upsampling is a process of adding zeros between the existing samples of the signal. It increases the sample ... Read More
