Function

MatrixRing ( alg^mat A, fld^fin E ) -> alg^mat, map()

Optional Arguments

Resultselt-ord^rat1 <= Results <= 2

Description

Given a matrix algebra A over the finite field F and a subfield E of F, return the matrix algebra N over E obtained from A by expanding each component of an element of A into the block matrix associated with it (i.e. so N is A considered as an E-matrix algebra), together with the E-isomorphism from A onto N.
