Generalizing Cramer's Rule: Solving Uniformly Linear Systems of Equations
Gema M. Diaz–Toca, Laureano González-Vega, Henri Lombardi · SIAM Journal on Matrix Analysis and Applications · 2005
Following Mulmuley's lemma, this paper presents a generalization of the Moore--Penrose inverse for a matrix over an arbitrary field. This generalization yields a way to uniformly solve linear systems of equations which depend on some parameters.
