Polynomial ordering in Maxima or MATLAB

EBMath

Hello,

I'm trying to use either MAXIMA or MATLAB for extended polynomial division.

In MAXIMA, I can use the grobner package and poly_pseudo_divide, but MAXIMA always seems to compute using lex order even if I set poly_monomial_order:'grlex. Any help here?

In MATLAB I can't even figure out how to set poly order or perform extended division. I would really like to be able to do this.

Thanks in advance for any advice!
