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
