#+CATEGORY: eigen
* Merge improvements from SVD qrstep to eigen - these should be
combined somehow as we only need one version of them.
* dlae2.f has better handling of 2x2 eigenvalues than our qrstep.c
* Document Jacobi eigen function, in particular that it only works for
symmetric matrices.
* add support for nonsymmv left eigenvectors?:
gsl_eigen_nonsymmv_params(const int lr)
to specify whether we should compute left/right eigenvectors (or both).
If they want both, we'll need a new function:
gsl_eigen_nonsymmv_lr(..., evec_r, evec_l, ...)
and
gsl_eigen_nonsymmv_lr_Z(...)
