Making maps between chain complexes -- information about the basic constructors

Basic constructors

Important computations creating new complex maps

Canonical maps between complexes

Some complexes come with canonical maps. To access the complex map, one uses canonicalMap(Complex,Complex). The following operations have associated canonical maps.

Random maps of chain complexes

The method randomComplexMap(Complex,Complex) allows one to construct random complex maps, random morphisms between complexes, and random null homotopies between complexes.
