Function

RationalReconstruction ( elt-alg^mat X ) -> elt-alg^mat

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(5); x_M := Matrix(x_F, 2, 2, [x_F.1^15, x_F.1^20, x_F.1^10, x_F.1^20]); RationalReconstruction(x_M);
