# dim(PolyhedralObject) -- computes the dimension of a cone, polyhedron, fan or polyhedral complex

## Description

 i1 : C = coneFromVData matrix {{2,3},{3,2}} o1 = C o1 : Cone i2 : dim C o2 = 2

Returns the dimension of a cone.

 i3 : F = hirzebruch 3 o3 = F o3 : Fan i4 : dim F o4 = 2

Returns the dimension of a fan. This is the maximal dimension of all cones of the fan.

 i5 : P = convexHull matrix {{1,-1,0,0},{0,0,1,-1}} o5 = P o5 : Polyhedron i6 : dim P o6 = 2

Returns the dimension of a polyhedron.

 i7 : PC = polyhedralComplex crossPolytope 3 o7 = PC o7 : PolyhedralComplex i8 : dim PC o8 = 3

Returns the dimension of a polyhedral complex. This is the maximal dimension of all polyhedra of the complex.
