the last matrix operation which well see is

Question

The last matrix operation which we'll see is matrix multiplication. Now there we will start along with two matrices, A_nxp and B_pxm. Remember hat A must have similar number of columns as B has rows. If this isn't true so we can't do the multiplication. If this is true after that we can perform the subsequent multiplication.

A_nxpB_pxm = (c_ij)_nxm

The new matrix will contain size n x m and the entry into the ith row and jth column, c_ij, is determined by multiplying row i of matrix A with column j of matrix B. it doesn't always make sense in words thus let's look at an illustration.
