文摘We in this paper give a decomposition concerning the general matrix triplet over an arbitrary divisionring F with the same row or column numbers. We also design a practical algorithm for the decomposition of thematrix triplet.

We give the expressions of the general solutions to the system and the matrix equation when thesolvability conditions are satisfied.
