Matrix multiplication program in C using arrays ~ mkniit ~ gniitsolution

Matrix multiplication program in C is used to perform a multiplication operation. This C program of matrix multiplication is totally depends on an arrays concept. This is based on three dimensional matrix formats. Now the matrix will be multiplied by only the mathematical form. Multiply the matrix in a form of (2×3). Before going to enter this topic, We’ve already published an article about Matrix addition source code in C.
