4.22.3.5 containsAsFace

Syntax:

containsAsFace( cone c1, cone c2 )

Type:

int

Purpose:

1 iff c1 contains c2 as a face; 0 otherwise

Example:

LIB"gfanlib.so"; intmat M[2][2]= 1,0, 0,1; cone c=coneViaPoints(M); intmat N1[1][2]= 1,1; cone d1=coneViaPoints(N1); containsAsFace(c,d1); ==> 0 intmat N2[1][2]= 0,1; cone d2=coneViaPoints(N2); containsAsFace(c,d2); ==> 1
