| ### Function RationalReconstruction ( elt-mdl^vec X ) -> elt-mdl^vec ### 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_V := VectorSpace(x_F, 7); x_v := x_V.2; RationalReconstruction(x_v); x_w := 23*x_V.2 - 3*x_V.3; RationalReconstruction(x_w);
