Excel is a strong tool with a variety of capabilities to increase productivity and automate processes. The capability to start actions depending on changes in cell values is one such feature. This tutorial will show you how to configure a pop-up message box to appear each time a cell value changes within a predefined range. This can be especially helpful if you want to get alerts or notifications right away if important data is changed or updated. You will discover how to leverage Excel's built-in functions and event triggers to make an interactive and dynamic spreadsheet by carefully following the ... Read More
In digital image processing, the gray level co-occurrence matrix, also known as GLCM, is a statistical method employed for holding the spatial relationship between pairs of pixels in a digital image. The gray level co-occurrence is a method of representing the way in which different combinations of pixel intensities are arranged within the image. It is mainly used to specify the texture property of an image and provide the information about the patterns, variations, and structures occurring in the pixel values within spatial regions of the image. What is Gray Level Co-Occurrence Matrix? As stated above, the gray level co-occurrence ... Read More
For data analysis, calculations, and organising massive volumes of information, Excel is a highly effective tool. The capability to cause pop-up message boxes based on specific circumstances is one of its useful characteristics. You may make your Excel spreadsheets interactive and user-friendly by establishing specified rules. This tutorial will show you how to make a pop-up message box that appears when a cell value satisfies a predetermined requirement, such as being greater or lower than a particular value. When validating data, advising users of vital information, or issuing alerts based on predetermined thresholds, this functionality can be especially helpful. Pop ... Read More
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 More
When using Excel, you could frequently find yourself working with different worksheets included within the same document. When someone views a specific worksheet, it's sometimes imperative to highlight important details or provide them important instructions. Using a message box that automatically appears when the desired worksheet is active or opened is one efficient way to accomplish this. In this lesson, we'll look at how to use this function and add a personalised message box to Excel, improving the user interface and making sure that crucial information is conveyed clearly. It's crucial to have a working grasp of VBA and a ... Read More
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 More
MATLAB is an object-oriented programming (OOP) language that allows us to create objects and define their behavior. In MATLAB, there is a data type called 'Handle' which is used to point an object. Handles in MATLAB also allows us to pass a function as an input argument of some other function. In MATLAB programming, the handles are passed by reference instead of value. Therefore, when any change is made in the object's property, it will reflect across all the references. The use of handles in a MATLAB program makes it more memory efficient because it does not require copying ... Read More
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 More
MATLAB is a high-level programming language that has capability to define a function that can accept a variable number of input arguments. In MATLAB, there is no need of defining any additional function or array to define a function with variable number of input arguments. How to Create a Function with Variable Number of Input Arguments in MATLAB? In MATLAB, when the keyword "varargin" is used in the function definition statement then it enables the function to take any number of input arguments. The "varargin" keyword is composed of "VARiable ARGument INput". It is important to note that the keyword ... Read More
In mathematics, the Fourier transform is a mathematical tool used for converting a function or signal from the time domain to the frequency domain. It is widely used in the field of signal processing, communication, image processing and analysis, etc. Before proceed to find the forward and inverse Fourier transformer of an image using MATLAB, let us get a brief overview of Fourier transform and its inverse. Forward Fourier Transform Fourier transform or Forward Fourier transform is a mathematical operation that is used to transform a signal from the time domain into the frequency domain. Therefore, the forward Fourier transform ... Read More
