Gilles commented on MATH-883:
-----------------------------
As of revision 1403591, the "isSymmetric" method from "MatrixUtils" is used.
> "getSquareRoot" in "EigenDecomposition"

> 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"|http://en.wikipedia.org/wiki/Square_root_of_a_matrix]).
> I would also suggest that the ["isSymmetric" method be moved from
> "EigenDecomposition" to "MatrixUtils"|MATH-884].
