Let P be an m x p matrix and Q be a pxn matrix. As you will find later in this book, M = P x Q is defined as Mi, j) = Ek, Pi,k) Qk, j). Write a function with header [M] = myMatMult(P,Q) that uses for-loops to compute M, the matrix product of P and Q. Hint: You may need up to three nested for-loops. Test Case 1 Test Case 2 4 4 4]; >> P = ones (3,3); >> M = myMat Mult (PP) M = 3 3 3 33 mmm >> P = [1 2 3 4; 5 6 7 8]; >> Q = [1 1 1; 2 2 2; 3 3 3; >> M = myMat Mult(P,Q) M = 30 30 30 70 70 70
