In this article, we learn how to change the green background of an image to some other background using MATLAB programming. The concept of changing a green screen background to another background involves the use of a technology called “chroma key”. This technology detects the absolute green color in the ... Read More

In this article, we will explore how to calculate variance in MATLAB. In mathematics, variance is a statistical tool used to measure the degree of dispersion of a set of data points around its average value. It is widely used to quantify the diversity or variability of a set of ... Read More

In this article, we will learn ow to calculate the impulse response of a system in MATLAB. Impulse response is an elementary concept used in analyzing and understanding the behavior of systems for an impulse input. It is mainly used to analyze the linear time invariant systems like digital filters, ... Read More

In this article, we will learn to calculate standard deviation in MATLAB. Standard deviation is a mathematical operation that gives the measure of variation in a set of data points. The standard deviation is used to study the dispersion of data around their average value. If a set of data ... Read More

In this article, we will explore how to calculate moving sum using MATLAB programming. But before that let us have a look into the concept of moving sum. What is Moving Sum? Moving sum is a mathematical operation that allows to calculate the sum of a set of numbers over ... Read More
