How To Create Video from Sequence of Images Using MATLAB?
In MATLAB, we can create a video from a sequence of images. In this tutorial, we will explore the steps involved in creating a video from an image sequence and will take an example to understand the concept practically. Process of Creating Video From a Sequence of Images The step-by-step process of creating a video from a sequence of images is explained below − Step (1) − Firstly, collect all the images in a folder that we want to use in the video. Step (2) − Read all the images using the 'imread' function and store them in a ...
Read MoreHow to Create a Textarea Component in MATLAB?
In MATLAB, we have a built-in GUI App Designer environment that allows us to develop various types of GUI (Graphical User Interface) applications with proper knowledge of software engineering and programming. In this MATLAB’s app designer environment, we can create various kinds of GUI components such as TextFields, Buttons, NumEditFields, Labels, Hypertext, and more. In this tutorial, we will explore how to create a TextArea Component in MATLAB app. TextArea Component in MATLAB In MATLAB, the TextArea is a GUI component allows application users to input a string of text. MATLAB provides a built-in function ‘uitextarea’ to create a TextArea ...
Read MoreHow to Create a New Matrix from All Possible Row Combinations in MATLAB?
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 MoreHow to Create a Hyperlink Component in MATLAB?
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 MoreDifference between Reluctance Motor and Induction Motor
Electric motors are present in the industry to help us to drive a lot of numbers of mechanical loads in the industry. They have a moving and stationary part to interact with the magnetic field and current to transform electric energy into mechanical energy. They have dominated the industry from automobiles to robotics and household to industrial applications. In this tutorial, we will explore the important differences between a reluctance motor and an induction motor. The most fundamental difference between a reluctance motor and an induction motor is that a reluctance motor operates on the principle of magnetic reluctance while ...
Read MoreDifference between inv() and pinv() functions in MATLAB
In this tutorial, we will discuss two important functions namely, "inv()" and "pinv()", used for matrix inversion in MATLAB. Since, the fundamental purpose of both the functions is the same, i.e. matrix inversion, but they are different from each other in many aspects. Hence, we will learn the important differences between 'inv()' and 'pinv()' functions. What is 'inv()' Function? In MATLAB, the 'inv()' function is a built-in function used to calculate the inverse of a non-singular square matrix. Therefore, if 'M' is a non-singular square matrix, then the function 'inv(M)' will return a new matrix 'B' for which 'I = ...
Read MoreDefinite Numerical Integration Using Quad in MATLAB
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 MoreCubic Spline Data Interpolation in MATLAB
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 ...
Read MoreUnleash Data Insights: Mastering AI for Powerful Analysis
Data holds essential information that informs decision−making in many different disciplines in the modern world. However, employing conventional methods might be challenging when working with a large volume of complicated data. Artificial intelligence (AI), a potent tool that has transformed how we analyze data, enters the picture in this situation. Organizations can use AI to find hidden patterns and trends and improve decisions. In this article, the impact of AI on data analysis is examined using case studies from India's healthcare, financial, agricultural, governance, and educational sectors. India's innovation landscape is changing as a result of AI, creating a bright ...
Read MoreCreate Cartesian Axes in MATLAB
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 ...
