Introduction The list data structure deals with the elements of different data types like integer numbers, float number or string. The elements need to be defined within the square brackets separated by comma. The Python language is primarily composed of different data structures and from it the list data structure is the most used one. The lists can hold elements of different data types and when they are assigned with some values they cannot be changed. In this article, we will be finding the maximum distance between the elements. Maximum Distance between the Elements The elements in the list are ... Read More
A Histogram is the graphical representation of the dataset distribution. It represents the data in the form of series of bars, where the range of data values represented by each bar and height of the bar represents the frequency of the data values defined within the range. These are mainly used to represent the distribution of the numerical data like grades in a class, distribution of the population or distribution of the incomes of the employees etc. In histogram, x-axis represents the range of data values, divided into intervals and the y-axis represents the frequency of the range of data ...

Singular Value Decomposition (SVD) is the matrix factorization technique which divides the matrix into three parts namely left singular matrix, a diagonal singular matrix and right singular matrix. SVD is powerful tool used in linear algebra and it has number of applications in data analysis, machine Learning and signal processing. This is mainly used to compute the rank of the matrix, as well as to perform the linear equations and performing the image compression and many more operations. Calculating Singular Value Decomposition If we compose a real or complex matrix A with the size m x n, then ... Read More
jQuery DataTables is a powerful plugin that provides advanced features for displaying and manipulating tabular data on the web. It offers a rich set of functionalities, including sorting, searching, pagination, and more. While DataTables simplifies the process of creating dynamic tables, effectively handling events within these tables is crucial to enhance user interactions and customize behavior. In this blog post, we will explore how to handle events using the jQuery DataTables plugin. We'll dive into both basic and advanced event handling techniques that will enable you to respond to user actions, perform custom operations, and create interactive data tables. Setting ... Read More
Covariance is the measure of two variables that defines how they are related to each other. In other words, it measures the extent to which one variable is associated with the changes in the other variable. When the covariance of the variables is positive, it implies that both variables are moving in the same direction i.e. if one variable tends to increase, as a result, the value of the other variable also increases. When the covariance of the variables is negative then it represents the two variables are moving in opposite direction i.e. if one variable increases the value ... Read More
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 image and omits it from the image. Then, we can apply another image or color as the background to the image. Algorithm The step−by−step process of changing the green screen background of an image with another background in MATLAB is explained below: Step (1) − Read the input image with ... 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 data points. We can compute variance of a data set by using the following formula: $\mathrm{Var=\frac{\displaystyle\sum\limits_{i=1}^n (x_i −\bar{x})^2}{n}}$ Where, xi is the individual data points, is the average of data set, and n is the total number of data points in the set. The following sections of this articles ... 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, electronic circuits, signal processing systems, control systems, and more. Impulse response of a system can be defined as follows: The response of a system when an impulse input signal is applied to it, is called the impulse response. It is denoted as h(t) for continuous time systems and h[n] for ... Read More
Chunked sum also known as partial sum or rolling sum, which is a process of calculating the sum of elements in a sequence such as list, array, or any iterable, in smaller chunks or subsets rather than calculating the sum of the entire sequence at once. Each chunk represents a group of consecutive elements from the sequence, and the sum is calculated for each chunk individually. For example, consider the sequence [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], and let's calculate the chunked sum with a chunk size of 3. Chunk 1: [1, 2, 3] → ... Read More
In mathematics, a bijection refers to a function that establishes a one-to-one correspondence between two sets. It means that each element in one set has a unique and distinct counterpart in the other set, and vice versa. In other words, a bijection ensures that there are no duplicates or missing elements in the mapping. In the view of programming, specifically Python, checking for a bijection often involves validating whether a one-to-one mapping exists between elements of two sequences or collections. For example, given two lists, A and B, we can check if there is a bijection between their elements by ... Read More
