matlab - How to solve a really nasty system of nonlinear equations -


i'm trying solve rather nasty system of equations consisting of 160 quadratic equations on 16 variables. know there tons of solutions (tons being @ least subvariety of dimension 6's worth) ones know aren't ones i'm interested in.

i tried using fsolve on matlab, fails when feed solution know works starting point (not time though, suspect not error in equation set, it's many equations handle reliably[mumble mumble... tolerance... mumble]). also, using normal solve function hilariously inadequate: if reduce system 20 quadratics, still takes quite awhile.

does know of computer algebra package or function can handle of magnitude?

thanks much!
