| ### Function RationalReconstruction ( elt-mdl X ) -> elt-mdl ### Description Given a matrix X over a prime finite field K, return true and the matrix over Q obtained from X by rational reconstruction of each of its entries if possible; return false otherwise. ### Examples x_F := FiniteField(13); x_E2:=KModule(x_F,2); x_e1 := x_E2.2; RationalReconstruction(x_e1); x_e2 := 3*x_E2.1 - 4*x_E2.2; RationalReconstruction(x_e2);
