A = 1:12;
B = 1:4;
I am looking for a function that performs multiplication as follows:
  1. Matrix B has 4 elements and matrix A has 12 elements. I want to multiply B with A, in a sequence of multiplying B with A(1:4), and next B with A(5:8), and so on.
  2. I want to perform this complete operation in one instance with some matlab function or vectorization without any loops involved
Could some one help me in this regard?

A = 1:12;
B = 1:4;
A = reshape(A,4,[])' ;
iwant = A.*B
iwant = 3×4
1 4 9 16 5 12 21 32 9 20 33 48
