Hi,
given a matrix A = (Aij) and an horizontal array b = (bj), with B and A of the same width, is there a command that returns a matrix C of the same size as A, and whose each element Cij = Aij * bj ?
I tried C = A .* b but it only works when A is an array as b.
Thanks!

try bsxfun:
C = bsxfun(@times,A,b);
