4.22.3.6 containsInSupport

Syntax:
containsInSupport( cone c1, cone c2 )
containsInSupport( cone c, intvec point )
Type:
int
Purpose:
1 iff c1 entirely contains c2 resp. iff c contains the given point, possibly on one of its facets; 0 otherwise
Example:
 
LIB"gfanlib.so";
intmat M[2][2]=
1,0,
0,1;
cone c=coneViaPoints(M);
containsInSupport(c,c);
==> 1
intmat N1[2][2]=
1,1,
0,1;
cone d1=coneViaPoints(N1);
containsInSupport(c,d1);
==> 1
intmat N2[2][2]=
1,1,
1,-1;
cone d2=coneViaPoints(N2);
containsInSupport(c,d2);
==> 0
intvec v1=0,1;
containsInSupport(c,v1);
==> 1
intvec v2=1,-1;
containsInSupport(c,v2);
==> 0
