If I do it this way though, is there a simple way to evaluate the polynomial? (ie is there a multivariable version of polyval) Not I'm aware of. It is not hard to write a general evaluator of multivariate polynomial. Writing a fast one is more challenging, and it seems it depends very much the structure of the polynomial and variables. > > Also in your script, I take it that every non zero element in abc represents a term. Is it possible to multiply each of these terms together? Why not? But so far I can't see in which kind of application one want to multiply them. Bruno
