A matrix is a two-dimensional array of many numbers arranged in rows and columns. And it is called as m X n matrix where m and n are the dimensions. In general, the multiplication of two matrices can be possible only if the number of columns in the first matrix is equal to the number of rows in the second matrix. Input Output Scenarios Assuming we have two input matrices A and B having 3X3 rows and columns. Then the resultant matrix will also have 3 rows and 3 column. [a, b, c] [j, k, l] [(a*j+b*m+c*p), (a*k+b*n+c*q), (a*l+b*o+c*r)] [d, ... Read More
