[Maxima-discuss] Constrained optimization

[Daniel V. <dan...@ya...>]

Hi All,
I'm trying to solve a constrained optimization problem using package optmiz like this:
load(optmiz)$
stapoints(x²*y,[],x²+y²-9)$

I get a cryptic error: UNIPOLY: argument must be a univariate polynomial;
The output however, seems to be correct:
map(ldisp,stapts)$

If I solve with algsys I get the same result:
sol:algsys(grad,decslkmults)$
map(ldisp,sol)$

Should I ignore the error?
Thanks,
Daniel Volinski
