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

Try
C = A ./ reshape( U2, [],1 );

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.
