MATLAB: Vectorizing the loop

Question

This code is similar to the histc function, but each element has weights associated with it. I'm looking to either use an alternate function or to vectorize it to make things faster

I have arrays A and B, and w is an array of weights associated with each element in A.

I'm hoping to calculate:

for i=1:length(B)
           x(i) = sum((A>B(i)).*w)
end

Any help is appreciated. Thanks.

Answer 1

x = w*bsxfun(@gt,A.',B)
