Subject [jira] [Updated] (MATH-235) Eigenvalues/eigenvectors of real asymmetric matrices
Date Mon, 28 Nov 2011 20:25:40 GMT


Luc Maisonobe updated MATH-235:

    Fix Version/s:     (was: 3.0)

Since nobody seems available to solve this soon, postponing again to 3.1.
Adding this would not break compatibility as it is a new feature, so it can be done at a minor
version release.

> 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
