Hi Steven, I'm actually trying to pass in a matrix X and get out the associated Vandermonde-like matrix as numbers. I thought of expressions because the loop itself is not trivial, we have to deal with all those combinatorial indexing somehow.
I have a code that generates the exponents of all the monomials as a tuple, but going from this tuple to the actual product is not clear to me. Let's say I have (0,1,0) meaning x^0*y^1*z^0 = y^1. How to do this conversion? Any trick? -Júlio
