This C program checks if a matrix is invertible. The key idea is to first find out the determinant of the given matrix. If it is a non-zero quantity, then the given matrix is invertible, otherwise there is no inverse of that matrix. Here is the source code of the C program to check for … Read more
This C program computes the determinant of a matrix. Here is the source code of the C program to find determinant of a matrix. The C program is successfully compiled and run on a Linux system. The program output is also shown below. #include<stdio.h> int main(){ int a[3][3], i, j; long determinant; printf("Enter the 9 elements … Read more
This is a C Program to check multiplicability of two matrices. Problem Description We have to write a C program to check whether the two matrices can be multiplied of not. We have to input the dimensions of two matrices i.e. number of rows and columns in each matrix and calculate whether they can be … Read more
Matrix multiplication in C is a technique of producing a single matrix from two matrices by multiplying them together. Constraint: For Multiplication of two matrices, the columns of the first matrix must be equal to the rows of the second matrix. Suppose the first matrix is of the order of [m ,n], so the second … Read more
This C program sorts a given array of integer numbers using Bubble Sort technique. The algorithm gets its name from the way smaller elements “bubble” to the top of the list. Because it only uses comparisons to operate on elements, it is a comparison sort. Time Complexity of this algorithm is O(n2). Here is the … Read more
This C program encodes a message using matrix multiplication. One type of code, which is extremely difficult to break, makes use of a large matrix to encode a message. The receiver of the message decodes it using the inverse of the matrix. This first matrix is called the encoding matrix and its inverse is called … Read more
This is a program to display upper triangular matrix. Problem Description This C Program displays the upper triangular matrix. Problem Solution 1. Create a matrix and define its elements. 2. To print the elements at upper triangle, run a nested for loop with two iterators(i and j) but print only those elements which have index … Read more
A Matrix is said to be a Lower Triangular matrix if all the Elements above the diagonal Elements are zero(0) or in other words All the elements including diagonal elements and below them are non- zero(≠0) Mathematically, if a Matrix M[m][n] is a Lower Trangular Matrix then it satisfies the condition: A[i][j] = 0 for … Read more
The following C program, using recursion, performs Matrix multiplication of two matrices and displays the result. We use 2 D array to represent a matrix and resulting matrix is stored in a different matrix. Here is the source code of the C program to display a linked list in reverse. The C program is successfully … Read more
This is a program to do the sum of the main & opposite diagonal elements of a MxN Matrix Problem Description This C Program finds the sum of the main & opposite diagonal elements of a MxN Matrix. The program accepts an MxN matrix. Then adds main diagonal of matrix as well as the opposite … Read more
