homomorphism -- get the homomorphism from element of Hom

homomorphism -- get the homomorphism from element of Hom

homomorphism f -- finds the matrix M <-- N corresponding to the element f.

This element should be a matrix f : Hom(M,N) <--- R^1, where Hom(M,N) has been previously computed, and R is the ring of M and N.

When A := Hom(M,N) is computed, enough information is stored in A.Hom to compute this correspondence.
