In this paper we expand some of the results of [8, 9, 10]. In fact, using the techniques of [8, 9, 10], we provide formulas for the full rank inner-outer factorization of a wide matrix-valued rational function G with H entries, that is, functions G with more columns than rows. State space formulas are derived for the inner and outer factor of G.
