Eigenvalues Eigenvectors of a complex matrix

[Riccardo Cecchetti]

I’m developing a Java application and I need to calculate the eigenvectors for a complex matrix.
I was able to download the html documentation of JLapack library and the .jar file.
I've imported all the the classes of "org.netlib.lapack" in my project but I can't see any class that can solve
the eigenvector problem for a complex matrix, like the class: CHETRD or ZHETRD.

Could you help me?
Could you send me some notes and some examples for the usage of complex matrices?
Which class should I use to get the eigenvalues and eigenvectors of the complex matrix?

Thanks in advance for your collaboration
Kind Regards
