4.23.1.12 numberOfConesOfDimension

Syntax:

numberOfConesOfDimension( fan f, int dimension, int orbit, int maximal )

Type:

int

Purpose:

number of cones (orbit=0) or orbits (orbit=1) of a given dimension; if maximal=0, then all cones are considered, if maximal=1, only maximal cones are considered

Example:

LIB"gfanlib.so"; fan f=emptyFan(3); ncones(f); ==> 0 intmat M[3][3]= 1,0,0, 0,1,0, 0,0,1; cone c=coneViaPoints(M); insertCone(f,c); numberOfConesOfDimension(f,0,0,0); ==> 1 numberOfConesOfDimension(f,0,0,1); ==> 0 numberOfConesOfDimension(f,1,0,0); ==> 3 numberOfConesOfDimension(f,0,0,1); ==> 0 numberOfConesOfDimension(f,2,0,0); ==> 3 numberOfConesOfDimension(f,2,0,1); ==> 0 numberOfConesOfDimension(f,3,0,0); ==> 1 numberOfConesOfDimension(f,3,0,1); ==> 1
