I have a cell

A = {[1 2; 3 4]; [5 6; 7 8]};

and a vector

b = [1; 2]

and I want to multiply each matrix in A by the corresponding value in b. Is it possible to do that without loops?

result = cellfun(@times,A,num2cell(b),'uni',false);

But this just moves the loops (which are part of cellfun) into the background.

No, it works for me. Perhaps your b was all zeros.

Simple and clean. Thanks!
