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

Use the bsxfun() function:
>> w = bsxfun(@rdivide,w,sum(w,1));

clear all, clc
rng(4151941)
w = randn(2, 3)
w1 = w./ repmat(sum(w),2,1)
w2 = bsxfun(@rdivide,w,sum(w))
e12 = norm(w1-w2)
Hope this helps.
Greg
