----------------------------------------------------------------
I included the test cases as attachments, but not as a simple test method. If
this is enough, please tell me.
Otherwise I'll see what I can do- I guess I could add my wrappers...
Give me till Friday- I didn't finish a vector-comparison method...
29/Oct- just found time to work on it- should be done by tomorrow...

QUESTION: If two algorithms produce two different sets of eigenvalues, are
they always the same values, but in a different order? Or might one be a
scaler multiple of the other?
If the eigenvalues are in a different order, will the rows of the eigenvectors
be in the same (different) order as the eigenvalues?
> Enhancement request: Complex Eigen Vectors

> Key: MATH-1557
> URL: https://issues.apache.org/jira/browse/MATH-1557
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.6.1
> Reporter: Randy Strauss
> Priority: Major
> Attachments: real-eigen-vectors-test-case.txt
>
>
> I have a real hamiltonian matrix and need to get complex eigenvalues and
> eigenvectors, just like MatLab produces (I'm moving code from MatLab to Java).
> I put a test case in the real-eigen-vectors-test-case.txt file, attached.
> (Meanwhile, I'll try the ojAlg library... The only other one I haven't
> investigated is JEigen, a wrapper around the C++ eigen library...)
> Thanks.
