D.13.2.49 insertCone
Procedure from library gfan.lib (see gfan_lib).
- Usage:
- insertCone(f,c[,b]); f fan, c cone, b int
- Assume:
- isCompatible(f,c)=1
- Return:
- none, inserts the cone c into f
if b=0, then skips check whether f and c are compatible
Example:
| LIB "gfan.lib";
fan f=emptyFan(3);
f;
