4.23.1.2 getCone
Syntax:
getCone( fan f, int dimension, int index, int orbit, int maximal )
Type:
- cone
Purpose:
- cone (orbit=0) or orbit (orbit=1) of a certain index (ranges from 1 to numberOfConesOfDimension(f,2,0,0)) in a given dimension; if maximal=0, all cones and orbits are considered, if maximal=1, only maximal cones and orbits are considered
Example:
| intmat M[3][3]=
1,0,0,
0,1,0,
0,0,1;
cone c=coneViaRays(M);
fan f=emptyFan(3);
insertCone(f,c);
getCone(f,2,1,0,0);
