Let's make a smaller, manageable version of what you are asking for. Suppose
A = [2 3; 5 7; 11 13]
A = 3×2
2 3 5 7 11 13
B = [4 6; 8 9; 10 12; 14 15]
B = 4×2
4 6 8 9 10 12 14 15
You want C that somehow equals the product of A and B. What is the result in this case?

If I take transpose of B and then multiply them, then I will get 3*4 matrix.

A = [2 3; 5 7; 11 13];
B = [4 6; 8 9; 10 12; 14 15];
C = A * B.'
C = 3×4
