[jira] [Commented] (MATH-235) Eigenvalues/eigenvectors of real asymmetric matrices

Gilles Sadowski (Jira)

    [ https://issues.apache.org/jira/browse/MATH-235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285889#comment-13285889 ]

Thomas Neidhart commented on MATH-235:
--------------------------------------

As already written on the mailinglist, the port has been committed to the trunk.

The integrated DecompositionSolver has not yet been adapted for complex eigenvalues, but the rest should be working. Any help and feedback is welcome!

> The EigenDecompositionImpl class contains methods to calculate the eigenvalues/eigenvectors of real symmetric matrices. However, for real asymmetric matrices there are currently no methods available to do this.
> It would be nice if commons-math could be enhanced to provide this extra functionality.
> Please note that the JAMA package contains a possible implementation in its EigenvalueDecomposition class.
