Miscellaneous Operations on Matrices

FrobeniusImage(A, e) : Mtrx, RngIntElt -> Mtrx
Given a matrix A over a finite field K of characteristic p, return the matrix obtained from A by mapping each entry Ai, j to (Ai, j)pe.
NumericalEigenvectors(M, e) : Mtrx, FldComElt -> SeqEnum
Given a square matrix M that is coercible into the complexes, and an approximation e to an eigenvalue of it, attempt to find eigenvectors. This function is for cases for which there are no numerical worries.
