TASK 04 This sample problem requires you to multiply 2 matrices and given the sum of the resultant matrix. For example, given the matrices M and N, you are required to multiple these matrices. Let A be the resultant matrix. Then your final answer should be element-wise sum of A. Note that the dimensions of M and N must match. The only operation allowed is transpose (i.e., changing the rows into columns and columns into rows). If the dimensions of N do not match with those of M, you try to take the transpose of N. Example 1 2 3 4 5 6 7 8 9 10 11 12 M= N- 1 0 3 4 5 6 1 8 0 0 0 12 A= 26 52 48 26 58 132 96 58 90 212 144 90 Answer is 26+52+48+26+58+132+96+58+90+212+144+90 = 858
