How to nest multiple parfor loops

Question

parfor is a convenient way to distribute independent iterations of intensive computations among several \"workers\". One meaningful restriction is that pa

You should be able to do this with bsxfun. I believe that bsxfun will parallelise code where possible (see here for more information), in which case you should be able to do the following:

bsxfun(@somefun,(1:6)',1:6);

You would probably want to benchmark this though.

Alternatively, you could do something like the following:

function parfor_allpairs(fun, num_rows, num_cols)

parfor i=1:(num_rows*num_cols)
    fun(mod(i-1,num_rows)+1,floor(i/num_cols)+1);
end

then call with:

parfor_allpairs(@somefun,6,6);
