Function

TransformationMatrix ( ord^num O, ord^num P ) -> elt-alg^mat, elt-ord^rat

Optional Arguments

Resultselt-ord^rat1 <= Results <= 2

Description

The transformation matrix from order O to order P, as an integral matrix and denominator (expressing what a vector element of O should be multplied by to obtain the corresponding vector element of P).

Examples

x_o := EquationOrder(X^2-5); x_O := MaximalOrder(x_o); TransformationMatrix(x_o,x_O);
