In this chapter, some more sophisticated interfaces to other software packages are described.

Note that this chapter is subject to change and extension as it is planned to expand simpcomp's functionality in this area in the course of the next versions. <#Include Label="homalg" /> Miscellaneous functions <#Include Label="tools" /> Property handlers As explained in Chapter , objects of the types SCSimplicialComplex, SCNormalSurface and SCLibRepository provide a set of property handlers for ease of access to simpcomp functions using these objects. Accessing these property handlers is possible via the .-operator.

For example, the f-vector of a simplicial complex c that is stored as a SCSimplicialComplex object can be accessed via the statement c.F; instead of writing the longer SCFVector(c);. See below for a list of all properties supported by objects of the types SCPolyhedralComplex, SCSimplicialComplex, SCNormalSurface and SCLibRepository (Note that the property handlers of SCPolyhedralComplex can be used by both SCSimplicialComplex and SCNormalSurface).
