I'm going to check. Actually, what I'm trying to do is find the
vertices of a polytope given by some hyperplanes (therefore the linear
equations). I know about polymake, but it can't do symbolic
Like
ax+by = 3
bx+dy=5
a,b,c,d constants
I know I could get a matrix and use linear algebra to get a fast
solution without worrying about symbolics
but when the systems are like
ax+by=p
cx+dy=q
with a,b,c,d constants, the vector in Ax=b is not numeric, so I turn
to symbolic solving
(actually those are simplificatinos, I'm doing 9-variable systems)
Thatnks for the hints, I will check the options you meantioned
