4.22.3.22 isSimplicial

Syntax:

isSimplicial( cone c )
isSimplicial( fan f )

Type:

int

Purpose:

1 iff the cone resp. fan is simplicial; 0 otherwise

Example:

LIB"gfanlib.so"; intmat M1[3][3]= 1,0,0, 0,1,0, 0,0,1; cone c1=coneViaPoints(M1); isSimplicial(c1); ==> 1 intmat M2[4][3]= 1,0,0, 0,1,0, 0,0,1, 1,1,-1; cone c2=coneViaPoints(M2); isSimplicial(c2); ==> 0 /***********************/ fan f=emptyFan(3); isSimplicial(f); ==> 1 intmat N1[3][3]= 1,0,0, 0,1,0, 0,0,1; cone d1=coneViaPoints(N1); insertCone(f,d1); isSimplicial(f); ==> 1 intmat N2[4][3]= 1,0,0, 0,1,0, 1,0,-1, 0,1,-1; cone d2=coneViaPoints(N2); insertCone(f,d2); isSimplicial(f); ==> 0
