Finding eigenvalues and Eigenvectors of a complex matrix

Hi,

I previously used TMatrixDEigen to obtain eigen-values and vectors of a real matrix.

The class accepts only real matrices, there is a similar class that accepts complex numbers?

Best regards,
Javier

Hi,

We don;t have support for complex matrix directly in ROOT, but you can use the GNU Scientific Library, for this.
See gnu.org/software/gsl/manual/ … gensystems
