Hi, I have a matrix A(7x1001) and a matrix B(1x7).

I'd like to divide the first row of A for the first colum(element) of B,

second row of A for the second column in B, and so on.

A and B are in attached

Oh, you're on a very old version, which doesn't have implicit expansion:

C = bsxfun(@rdivide, A, B(:));

However, again, why isn't B a column vector (7x1) instead of a row vector (1x7)? This would avoid the transpose/reshape and would make it consistent with the shape of A.
