facets( cone c )
facets( polytope p )

Type:

bigintmat

Purpose:

inner normal vectors of the facets of the cone

Example:

LIB"gfanlib.so"; intmat M1[2][2]= 1,0, 0,1; cone c1=coneViaPoints(M1); bigintmat F1=facets(c1); print(F1); ==> 0,1, ==> 1,0 intmat M2[2][2]= 1,1, 0,-1; cone c2=coneViaPoints(M2); bigintmat F2=facets(c2); print(F2); ==> 1,-1, ==> 1, 0
