4.23.4.27 intersectCones

Syntax:
intersectCones( cone c1, cone c2 )
Type:
cone
Purpose:
the intersection of the two cones
Example:
 
intmat M1[2][2]=
1,0,
0,1;
cone c1=coneViaRays(M1);
intmat M2[2][2]=
1,1,
1,-1;
cone c2=coneViaRays(M2);
intmat M3[2][2]=
1,0,
0,-1;
cone c3=coneViaRays(M3);
cone c12=intersectCones(c1,c2);
c12;
==> AMBIENT_DIM
==> 2
==> INEQUALITIES
==> 0,1,
==> 1,-1
==> EQUATIONS
==> 
print(rays(c12));
