Matlab brute force approach

I want to use Matlab to find the best allocations in some optimization problems. I'm trying to write a script to brute force all possible allocations so:

w1 + w2 + w3 = 1

w1 - 0:1, with step 0.01

I'm trying to use loop function, but I can't figure out how it should work.

See ndgrid(). If possible, vectorize your function; if not, consider using arrayfun()

Or, use bsxfun with w1 and w2 as the two arrays (since w3 = 1 - (w1 + w2))
