D.13.2.6 codimension
Procedure from librarygfan.lib (see gfan_lib).
- Usage:
- codimension(c); c cone
codimension(f); f fan
codimension(p); p polytope - Return:
- int, the codimension of the input
LIB "gfan.lib"; intmat M1[1][2]= 1,0; cone c1=coneViaPoints(M1); codimension(c1); ==> 1 intmat M2[2][2]= 1,0, 0,1; cone c2=coneViaPoints(M2); codimension(c2); ==> 0 fan f = emptyFan(2); codimension(f); ==> -1 insertCone(f,c1); codimension(f); ==> 1 insertCone(f,c2); codimension(f); ==> 0 |
