MATLAB: Error using ==> rdivide

Question

For

w = randn(10, 51300);
w = w./ sum(w,1);

i get

??? Error using ==> rdivide
Matrix dimensions must agree.

For each column of 10 elements, I wish to divide each element by sum(w,1).

How can I do this without using a for loop? thanks

Answer 1

Use the bsxfun() function:

>> w = bsxfun(@rdivide,w,sum(w,1));
