In MATLAB, we can create various types of GUI components like EditField, buttons, hyperlink, image, etc. In this tutorial, I will explain how can you create an image component in MATLAB programming. But before that let us first get an overview of image component in MATLAB. What is Image Component in MATLAB? In MATLAB, Image Component is a GUI (Graphical User Interface) component used to show an image in a MATLAB application. This component is widely used in applications where it is required to handle images like in image processing and analysis. To create an image component, MATLAB provides a ... Read More
In MATLAB, appending is nothing but the process of adding data to a text file which already exists in the memory or workspace. In MATLAB, there is a built-in function 'fprintf' which is used to append or add data to a file. The 'fprintf' function allows users to add or writer formatted data to a text file. By default, this function adds the data to the end of the text file. Let us now see the step-by-step process to append data to a file in MATLAB. How to Append Data to a File? The step-by-step process to append ... Read More
A type of noise signal which has a flat power spectral density (PSD) across all frequencies is referred to as white gaussian noise or white noise. In this tutorial, I will explain how to add white gaussian noise to signal using MATLAB. But before that let get a brief overview of white gaussian noise. What is White Gaussian Noise? A type of noise signal which has equal energy at all frequencies within a specified frequency range is termed as white gaussian noise. Therefore, white gaussian noise has a flat power spectral density (PSD) across all frequencies. In the case of ... Read More
MATLAB allows us to create graphical user interface (GUI) applications without proper knowledge of coding. It has a built-in component library containing a wide range of GUI components such as buttons, edit fields, numeric edit fields, hyperlinks, and many more. In this tutorial, I will explain how you can create an EditField component in MATLAB. What is an EditField Component in MATLAB? In MATLAB, the EditField component is a graphical user interface (GUI) component which is used to allow your users to input and edit text or number. The EditField component is one the fundamental GUI components used to build ... Read More
MATLAB is an efficient tool to process and manipulate digital images. In MATLAB, a digital image is specified as a two-dimensional matrix where the elements of the matrix represent the pixel intensity of the image. When the pixel intensity of a digital image is represented as a 2D matrix, then it is known as spatial domain. For any digital image specified in 2D matrix form or spatial domain, there is a term 'spatial resolution' which describes how sharply we can see the objects in the image. Also, there is another term 'brightness resolution' which describes pixel intensity of the image. ... Read More
MATLAB is a robust and high-level programming language extensively used in engineering and scientific fields for system design. The most important fact about MATLAB is that it provides an easy-to-use graphical user interface (GUI). MATLAB has a built-in App Designer tool that allows users to develop a variety of applications that seamlessly translate their concepts into user-friendly GUIs. Overall, MATLAB is an invaluable tool for conveying complex information in a simplified and accessible manner. In this tutorial, we will explore how to create a GUI App using App Designer in MATLAB. How to Create Apps using MATLAB App Designer? The ... Read More
In MATLAB, a matrix is a 2D array that is mainly used store numerical data. MATLAB allows users to perform several different types of mathematical operations on matrices. This tutorial is primarily meant for explaining two matrix operations namely, finding indices of maximum and minimum elements of the matrix. However, MATLAB does not provide any direct method for finding the indices of maximum and minimum value of a matrix, but we can do this by using a combination of different built-in functions. For example, to find the index of maximum value of matrix, we can use a combination of the ... Read More
In MATLAB, a cell array is a type of data structure used to hold data of different data types and sizes. In short, a cell array allows us to store different types of data like numbers, characters, strings, arrays, and more. In a cell array, each cell can contain a specific type of data. Cell array is a powerful tool to handle heterogeneous data. In MATLAB, the curly braces '{}' are used to create a cell array, i.e. CellArray = {10, 'TutorialsPoint', [2 3 4]}; Hence, cell arrays play a vital role, when we need to store different types ...

MATLAB is a powerful tool to manipulate matrices. In this article, we will explore how to extract subsets of consecutive entries in a matrix using MATLAB. But before that let's first get an overview of subsets of consecutive entries in a matrix. In a matrix, a set of elements that located in either rows or columns, or both in a sequence is referred to as a subset of consecutive entries in the matrix. The subsets of consecutive entries in a matrix can be extracted by specifying a range of columns and rows. The subsets of consecutive entries in a matrix ... Read More
Double Interpolation is a mathematical method used to calculate values within a set of data points. It is basically an advanced version of interpolation, as it is used to interpolate a function that depends on two variables. In other words, the double interpolation is a method of estimating value of a function within a set of a data points by combining two distinct interpolation processes. In this tutorial, I will explain how to calculate double interpolation using lookup table in MATLAB. But before let's get a basic overview of terms "interpolation", "double interpolation", and "lookup table". What is Interpolation? ... Read More
