D.13.2.25 inequalities
Procedure from library gfan.lib (see gfan_lib).
- Usage:
- inequalities(c); c cone
inequalities(p); p polytope
- Return:
- bigintmat, the inequalities of c resp p
- Note:
- neither unique nor irredundant, unless c resp p in canonical form
Example:
| | LIB "gfan.lib";
intmat M1[2][2]=
1,0,
0,1;
cone c1=coneViaPoints(M1);
bigintmat I1=inequalities(c1);
print(I1);
==> 0,1,
==> 1,0
intmat M2[2][2]=
1,1,
0,-1;
cone c2=coneViaPoints(M2);
bigintmat I2=inequalities(c2);
print(I2);
==> 1,-1,
==> 1, 0
