In this case (red digits): So if you want to multiply the vector a with the matrix b (2x2) this should be c = b*a, where c will be a 2x1 vector.

John Paul Gave A Nice Concise Answer, But I'll Add A Little Bit More Explanation For Learning Purposes.

A = np.array([1,0]) and get a 1x2 result with. We take the dot product between the first row of matrix one and the column in matrix two two give us the 1st row of our new matrix. Suppose 1st matrix is of size ab and 2nd matrix is of size cd ac correspond to row and bd correspond to column.

So The Result Will Be A 2 ×1.
