D.13.2.36 rays
Procedure from librarygfan.lib (see gfan_lib).
- Usage:
- rays(c); c cone
- Return:
- bigintmat, generators of the rays of c, orthogonal to its lineality space
LIB "gfan.lib"; intmat M1[2][2]= 1,0, 0,1; cone c1=coneViaPoints(M1); bigintmat R1=rays(c1); print(R1); ==> 1,0, ==> 0,1 intmat M2[3][2]= 1,0, 0,1, -1,0; cone c2=coneViaPoints(M2); bigintmat R2=rays(c2); print(R2); ==> 0,1 |
