Function

MatrixAlgebra ( fld^fin F, fld^fin E ) -> alg^mat, map()

Optional Arguments

Resultselt-ord^rat1 <= Results <= 2

Description

Given a finite field F and a subfield E of F such that F is of degree n over E, return the matrix algebra A of degree n over E which is isomorphic to F, together with the isomorphism from F onto A such that the generator of F over E is mapped to the generator of A.

Examples

x_E:=FiniteField(5); x_Ey:=PolynomialAlgebra(x_E); x_F:= Extension(x_E,x_Ey.1^2+2); MatrixAlgebra(x_F,x_E);
