Description

I propose to add a method "getSquareRoot" in class "EigenDecomposition" (package "o.a.c.m.linear").
When assuming that the matrix is symmetric and positive definite, the implementation is trivial (see "By diagonalisation").

I would also suggest that the "isSymmetric" method be moved from "EigenDecomposition" to "MatrixUtils".
