>                 Key: MATH-882
>                 URL: https://issues.apache.org/jira/browse/MATH-882
>             Project: Commons Math
>          Issue Type: Improvement
>    Affects Versions: 3.1
>            Reporter: Thomas Neidhart
>             Fix For: 4.0

>
> The current DecompositionSolver in EigenDecomposition only supports real eigenvalues. With the recently added support for non-symmetric matrices, also complex eigenvalues are possible as result of the decomposition.
> In such a case, an MathUnsupportedOperationException is thrown when trying to get a DecompositionSolver with getSolver().
