Hi,
I have a A(nxa) matrix and a B(1xp) matrix. I'm trying to multiplicate A by B, creating a C(nxaxp) matrix (3D), where the reality nxa is multiplied by each value of p, creating p realities.
Any direct/efficient way of doing this without the for loop?
Thank you very much,

C = bsxfun(@times,A,reshape(B,1,1,[]));
