D.13.2.16 dimension
Procedure from library gfan.lib (see gfan_lib).
- Usage:
- dimension(c); c cone
dimension(f); f fan
dimension(p); p polytope
- Return:
- int, the dimension of the input
Example:
| LIB "gfan.lib";
intmat M1[1][2]=
1,0;
cone c1=coneViaPoints(M1);
dimension(c1);
==> 1
intmat M2[2][2]=
1,0,
0,1;
cone c2=coneViaPoints(M2);
dimension(c2);
==> 2
fan f = emptyFan(2);
dimension(f);
==> -1
insertCone(f,c1);
dimension(f);
==> 1
insertCone(f,c2);
dimension(f);
==> 2
