D.8.4.1 nt_solve
Procedure from library ntsolve.lib (see ntsolve_lib).
- Usage:
- nt_solve(gls,ini[,ipar]); gls,ini= ideals, ipar=list/intvec,
gls: contains the equations, for which a solution will be computed
ini: ideal of initial values (approximate solutions to start with),
ipar: control integers (default: ipar = [100, 10])
| ipar[1]: max. number of iterations
ipar[2]: accuracy (we have the l_2-norm ||.||): accepts solution sol
if ||gls(sol)|| < eps0*(0.1^ipar[2])
where eps0 = ||gls(ini)|| is the initial error
|
- Assume:
- gls is a zerodimensional ideal with nvars(basering) = size(gls) (>1)
- Return:
- ideal, coordinates of one solution (if found), 0 else
- Note:
- if printlevel >0: displays comments (default =0)
