  | #### D.16.1.3 groebnerCone `Syntax:` `groebnerCone(` poly g, intvec v `)` `groebnerCone(` poly g, bigintmat v `)` `groebnerCone(` ideal I, intvec v `)` `groebnerCone(` ideal I, bigintmat v `)` `Assume:` I reduced standard basis, v contained in the maximal Groebner cone of the current ordering `Type:` cone `Purpose:` the euklidean closure of all weight vectors with respect to whom the initial form of g or the initial ideal of I coincides with the initial form or the initial ideal with respect to v. `Example:`
      LIB "gfanlib.so";
      ring r = 0,(x,y),dp;
      poly g = x+y+1;
      cone C = groebnerCone(g,intvec(1,1));
      rays(C);
      ==> 1,1

      ideal I = x2-y3,x3-y2-x;
      I = std(I);
      C = groebnerCone(I,intvec(1,1));
