In this tutorial, we will write a C# program to subtract two matrices. For matrix Subtraction, we require two matrices and both the matrices must be a square matrix.
Explanation:
We first take the user input for a number of rows and the number of columns. Then passing rows and columns, we take input for two matrices A & B. Then those matrices are subtracted as shown in the following program. And lastly, the result matrix is displayed.
