This program takes two dimensional arrays which represents the matrices and multiply them together. It go’s through each column of the first matrix one row at a time while multiplying the columns with each matching row of the second matrix one column at a time and adding their products to the total. And add the totals to the corresponding cells of the new matrix and return the new matrix.
