Randomly Shuffle Rows in MATLAB Matrix
MATLAB is a great tool to process matrices. It provides a large number built-in functions and processing methods that we can use to manipulate our matrices just by writing a small piece of MATLAB codes. Such an operation that we can perform on matrices in MATLAB is random shuffling of rows of a matrix. In this tutorial, I will explain how you can randomly shuffle rows of a matrix using MATLAB. Randomly Shuffle Rows of a Matrix in MATLAB MATLAB is a complete solution to manipulate matrices using computers. In MATLAB, we can very easily shuffle rows of a matrix ...
Read MoreHow to Pop Out a Warning if Duplicate Entered in an Excel Column?
It's critical to have a mechanism in place to identify and notify you about any duplicate values because duplicate data can frequently result in mistakes and inconsistencies in your spreadsheet. This tutorial will show you how to set up a warning message that will pop up if an entry is made twice in a certain column of your Excel worksheet. This course will provide you with the knowledge and abilities to successfully spot and manage duplicate values in your data, regardless of your level of Excel proficiency. So, let's get started and give you the capability to quickly find and ...
Read MoreGray Scale to Pseudo Color Transformation in MATLAB
MATLAB provides an easy and efficient way of processing images. In this tutorial, we will explore how to perform gray scale to pseudo color transformation in MATLAB. In MATLAB, the gray scale to pseudo color transformation is an image processing technique which is used to create a visually appealing image by mapping the intensity values of the gray scale image to a specific color. If we want to convert a gray scale image to a pseudo color image using MATLAB, then we can use a built-in function in MATLAB, which is ‘colormap’ and a color map matrix. Now, let us ...
Read MoreHow to Create an Image Component in MATLAB?
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 MoreHow to Append Data to a File in MATLAB?
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 MoreHow to add White Gaussian Noise to Signal using MATLAB?
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 MoreHow to Add an EditField Component in MATLAB?
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 MoreHow Spatial Resolution of a Digitized Image is Different from Brightness Resolution in MATLAB?
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 MoreCreating Apps Using App Designer in MATLAB
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 MoreFind Indices of Maximum and Minimum Value of Matrix in MATLAB
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 ...
