7.7.17.0. ncHom
Procedure from library nchomolog.lib (see nchomolog_lib).
- Usage:
- ncHom(M,N); M,N modules
- Compute:
- A presentation of Hom(M',N'), M'=coker(M), N'=coker(N)
- Assume:
- M' is a left module, N' is a centralizing bimodule
- Note:
- ncHom(M,N) is a right module, hence a right presentation matrix
is returned
