Thanks for all the ideas. I will check out your codes. I do
indeed need every permutation of the solution vectors. 

I'm working on some sparse grid codes in MATLAB and the
interpolants on a sparse grid of order N are constructed from
all possible combinations of tensor product interpolants
where the indices of the constituent dimensions add up to N. 

Thanks for the suggestions!
