Hi Willem, i find it. I will try them tomorrow since i am not sure whether parameter is "poly".
SingularLibrary( "standard.lib" );I:= Ideal( R, [f1,f2,f3,f4] );;SingularInterface( "stdhilb", [ f1,f2,f3,f4 ], "def");SingularInterface( "stdhilb", [ f1,f2,f3,f4 ], "poly"); Regards, Martin Date: Wed, 24 Sep 2014 18:34:34 +0200 Subject: Re: [GAP Forum] how to use the hilbert function after loadpackage singular From: [email protected] To: [email protected] CC: [email protected] Dear Martin, Forum, The "singular" package provides direct access to only few functions of Singular. The main function is GroebnerBasis, for computing Groebner bases. One can try using other functions by using SingularInterface of the singular package. The manual of the singular package explains how to use it.
