In MATLAB, a matrix is nothing but a 2D (two-dimensional) array of numbers arranged in multiple rows and columns. Matrix is the most elementary data structure in MATLAB programming which is utilized to store and manipulate data. In this tutorial, we will learn how to create a new matrix from all possible row combinations in MATLAB. For this, we can use MATLAB's built-in function 'randperm'. The 'randperm' function will randomly select a row index and create a new matrix. Algorithm The step-by-step process to create a new matrix from all possible row combinations is described below − Step (1) ... Read More

MATLAB allows us to create matrices by using nested loops. In this tutorial, we will learn how to create a matrix using a nested loop in MATLAB. In MATLAB, creating a matrix using nested loop is a straightforward two step process. The step-by-step process to create a matrix using a nested loop is explained below − Step (1) − Initialize the matrix and specify the loop limits depending on the number of ... Read More

In MATLAB, we can use the MATLAB's built-in GUI environment 'App Designer' to create a hyperlink component. The App Designer Environment of MATLAB allows to create several types of GUI components like hyperlink, buttons, sliders, text fields, etc. To create a hyperlink component in MATLAB, we can use a built-in option 'uihyperlink'. This function creates a GUI hyperlink component in MATLAB. This function allows users to navigate across web resources with a single click. The 'uihyperlink' function creates a hyperlink object in a MATLAB app. The 'uihyperlink' function can have the following syntaxes. (1). Create Hyperlink Object with Default Properties ... Read More

Discrete Fourier transform and Inverse discrete Fourier transform are two mathematical operations used to analyze functions and signals in the frequency domain. Both DFT and IDFT are widely used in the field of digital signal processing to synthesize and analyze the digital signals. Let's discuss a bit more about the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) individually. What is Discrete Fourier Transform (DFT)? In mathematics, the discrete Fourier transformation (DFT) is a transformation technique that is used to convert a sequence of discrete datapoints from time domain to frequency domain. DFT basically converts a sequence of ... Read More

In mathematics, differential or derivative is one of the fundamental operations used to determine the rate of change of a function. Therefore, derivatives are crucial to analyze various scientific and engineering processes or functions. We can perform derivates using various mathematical tools like MATLAB. In this tutorial, we will explore how to calculate derivative of a given mathematical function using MATLAB. But before that let's first get an overview of derivative. What are Derivatives? Derivative is a mathematical operation used to compute the rate of change occurring in a function or a process. In terms of geometry, derivates is defined ... Read More

In this tutorial, we will learn how to calculate definite numerical integration using Quad function in MATLAB. But before that, let us first understand what is definite numerical integration. What is Definite Numerical Integration? In mathematics, a method of determining the approximate value of the definite integral of a function over a certain interval is termed as definite numerical integration. Where, the definite integral specifies the signed area under the curve of a function within the specified interval. The definite numerical integration is beneficial in approximating the value of a definite integral of a function when it is not possible ... Read More

In this tutorial, we will define various import options for table in MATLAB. The import options allow us to bring data into a table or another data format. For example, we can utilize this option to read data from a given spreadsheet file "sample.xlsx" into MATLAB in the form of a table. By using the import options, we have the ability to open the designated file, select the desired output format and date range, and then save our selections. Upon clicking the "Import Selection" option, the specified data can be easily integrated into the MATLAB workspace. Additionally, the tabular ... Read More

In mathematics, the cubic spline data interpolation is a way of calculating values between data points of a given data set. This technique is widely used when we want to plot a smooth curve passing through these data points. In MATLAB, we can calculate the cubic spline data interpolation by using any of two built-in functions namely, 'spline' or 'interp1'. Syntax Where, the syntax of the 'spline' function is, I = spline(x, y, query); Here, 'x and 'y' are the vectors containing input data points required for interpolation, and 'query' is the vector that contains data points at which ...

When a figure is constructed in MATLAB as a graphical component, the cartesian axes are automatically added; however, MATLAB has a function, the 'axes()' function, to carry out the specific task. Cartesian axes are produced in a figure by this function. When several cartesian planes are required in a single figure component, it is quite helpful. In this tutorial, we will explore how to create cartesian axes in MATLAB. Now, let us discuss different syntaxes of the 'axes' function to create cartesian axes with the help of example programs. (1). Create Default Cartesian Axes In MATLAB, we can use the ... Read More
