This is a Java Program to Accept a Matrix of Order MxN & Interchange the Diagonals. Enter the elements of array as input. Now we use loops and if else condition to interchange the two diagonals of the matrix. Here is the source code of the Java Program to Accept a Matrix of Order MxN … Read more

Matrix addition in Java is used to add two matrices. i.e. calculate and print the sum of them. Example: Given two matrices of the same size, this program will add the corresponding elements of each matrix and print the result. Input: First Matrix: Second Matrix: Output: + = = Problem Description Write a C program … Read more

This is a Java Program to Determine if a given Matrix is a Sparse Matrix. If the number of zero elements are more than the non-zero elements of the matrix then it is known as Sparse Matrix Enter the elements of array as input. Now we use loops and if else condition to check for … Read more

Matrix multiplication in Java is the process of multiplying two matrices using the dot product of rows and columns, calculated using nested for loops. The resulting matrix has the same number of rows as the first matrix and the same number of columns as the second matrix. Constraint: For Multiplication of two matrices, the columns … Read more

This is a java program to LU Decomposition of a given matrix. LU decomposition is the process of reducing single matrix into 2 matrices such that, upon multiplication we get the original matrix, having property that one of them is lower trinagular matrix and other one is upper trinagular matrix. Here is the source code … Read more

This is java program to convert the system of linear equations to matrix form. The input is the coefficient of each variable and constant. Class rearranges them and converts them into matrix form, which aids solving them. Here is the source code of the Java Program to Represent Linear Equations in Matrix Form. The Java … Read more

This is a java program to encrypt a matrix using a key. The key is hidden and kept secret and inverse copy of the key is provided to the receiver, with which he/she can decrypt the matrix. The operation performed is matrix multiplication. Here is the source code of the Java Program to Perform Encoding … Read more

This is the Java Program to Find the Modulus of a Matrix. Problem Description Given a square matrix, find and print the modulus(determinant) of the matrix. Example: Matrix: 1 2 3 4 5 6 7 8 9 Output: Modulus = 0 Problem Solution The algorithm for calculating modulus of 3*3 matrix is x=(matrix[0][0] * (matrix[1][1] … Read more

This is the java program to find whether the vectors entered by users form the basis for the given dimension. The result for the same can be obtained by checking whether the determinant of the matrix formed by vectors is zero or not. If the determinant is non zero its forms the basis for the … Read more
