Using C and MPI, Implement matrix-vector multiplication using a block-submatrix distribution of the matrix. Assume that the vectors are distributed among the diagonal processes. Once again, you can have process 0 read in the matrix and aggregate the sub-matrices before sending them to the processes. Assume comm_sz is a perfect square and that the square root of comm_sz evenly divides the order of the matrix.
