Tests if a Cone is pointed, i.e. the lineality space is 0. A Fan is pointed if one of its Cones is pointed. This is equivalent to all Cones being pointed.
i1 : C = coneFromHData(matrix{{1,1,-1},{-1,-1,-1}}) o1 = C o1 : Cone |
i2 : isPointed C o2 = false |
i3 : C = intersection{C, coneFromHData(matrix{{1,-1,-1}})} o3 = C o3 : Cone |
i4 : isPointed C o4 = true |
The object isPointed is a method function.
