The aim of this article is to implement a program C++ program to check if all rows of a matrix are circular rotations of each other. Here is a small glimpse on what a matrix exactly is. The rectangular array of symbols or numbers organized in rows and columns is known as a matrix. A matrix can be of many distinct types, including row, column, horizontal, vertical, square, diagonal, identity, equal, and singular. Addition, subtraction, as well as multiplication are the three fundamental matrix operations. The goal is to determine whether all rows of a matrix of size n*n ... Read More

The aim of this article is to implement a program C Program To Write Your Own atoi(). Before we begin, let us take a deeper understanding of what an atoi() function is all about. This will help in writing the program as well as understanding the concepts pretty much easier. To the ones who are not much aware of what an atoi() function is. Here you go. The atoi() function changes a string of elements into an integer value. The string that is entered is a string of characters that has the potential to become a numeric value of the ... Read More

The aim of this article is to implement a program to minimize a given number by swapping adjacent digits with odd differences. The goal is to determine the lowest amount that can be created from a string of size N indicating an integer using only the characters '1', '2', and '3' by exchanging adjacent characters any number of times. As we all know, a string is a group of characters that ends with the null character "0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in ... Read More

The aim of this article is to implement a program to check if a given String is K-periodic for all K in range [1, N]. The aim is to determine whether the supplied string is K-periodic provided the string s and the integer K. If a string repeats the sub-string str[0... k-1], it is said to be k-periodic; for example, the string "ababab" is 2 periods long. Print Yes if the supplied string is k-periodic; otherwise, print No. If a character string can be created by concatenating at least one repeats from another string of length k, it is said ...

The aim of this article is to implement a C++ Program to Find Lexicographically minimum string rotation. Coming on to the definition of string, a string is a group of characters that ends with the null character "0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0." Finding the rotation of a string that has the lowest lexicographical order among all feasible rotations is known to be the lexicographically minimal string rotation as well as lexicographically smallest circular ...

Electrical Conductivity is an important term used in electrical engineering to understand the behavior of a material and electric current flowing through it. Electric conductivity is the property of a material that provides ease in the flow of electric current through the material. Read this article to get a detailed understanding of "electric conductivity", from its definition to principle and its applications. Let us start with the basic definition of electrical conductivity. What is Electrical Conductivity? Electrical conductivity is defined as the property that provides ease in the flow of electric current (movement of electrons) through a material. Electrical conductivity ... Read More

Read this tutorial to learn the method of swapping two elements in each row of a matrix without using loop in MATLAB. MATLAB is a powerful to manipulate matrices. We can perform various operations on matrices using MATLAB. In MATLAB, we can swap any two elements in each row of a matrix using the "matrix indexing method". This method of swapping two elements in rows of a matrix is explained below with the help of an example. How to Swap Two Elements in Each Row of Matrix without using Loop In MATLAB, we can use the matrix indexing to swap ... Read More

Root Mean Square Error (RMSE) is an error estimation technique used to calculate the difference between estimated values and actual values. This method provides the average value of errors as a single value. We can use MATLAB to calculate the root mean square error. For this, MATLAB provides various built-in functions. In this tutorial, I will explain how to calculate the Root Mean Square Error (RMSE) in MATLAB. What is Root Mean Square Error (RMSE)? The root mean square error (RMSE) is a method of measuring error or accuracy of a predictive tool or model. It is calculated by finding ... Read More

Reduced row echelon form (rref) matrix is a simplified matrix used to solve a system of linear equations. MATLAB provides some built-in functions to find the reduced row echelon form matrix of a given matrix. Read this article to learn these methods of finding the reduced row echelon form matrix of a given matrix using MATLAB. Before that let’s get an overview of rref matrix and its properties. What is a Reduced Row Echelon Form Matrix? In linear algebra, the reduced row echelon form matrix, also known as rref matrix, is a special and simplified matrix used to solve systems ... Read More

When we multiply two N-dimensional matrices along each dimension or page of the two matrices, then it is called page-wise matrix multiplication. Page-wise matrix multiplication is mainly performed in the case of 3-dimensional matrices. Go through this tutorial to learn the methods of performing page-wise matrix multiplication using MATLAB. What is Page-Wise Matrix Multiplication? When two N-dimensional matrices are multiplied along each dimension of the two matrices, then this type of matrix multiplication is called the page-wise matrix multiplication. It is basically the element wise multiplication of two 3D matrices along a specific dimension or page in a 3D matrix. ... Read More
