Subject [jira] [Created] (MATH-882) Complete decomposition solver support in EigenDecomposition for complex eigenvalues
Date Tue, 23 Oct 2012 20:57:12 GMT
Thomas Neidhart created MATH-882:
------------------------------------

             Summary: Complete decomposition solver support in EigenDecomposition for complex
eigenvalues
                 Key: MATH-882
                 URL: https://issues.apache.org/jira/browse/MATH-882
             Project: Commons Math
          Issue Type: Bug
    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().
