Re: nonsymm eigenvalues...

Hi, I'm just starting to write a little code snippet to find eigenvalues
and vectors for a non-symmetric, real matrix and am not finding the
nonsymm functions or include files as described in the current online
manual. My current version is 1.8-1.1 (FC 6). Were these functions not
available in that release? Would upgrading help or is the problem
elsewhere (as in I'm not looking at the right place in e.g.
gsl/gsl_eigen.h)?
Also, what is likely to happen if I call the symmetric routines for a
nonsymmetric matrix? They seem to "work" and still produce eigenvalues
and eigenvectors. Are those garbage?
Sorry to ask what are probably elementary questions, but the last time I
actually took a course on linear algebra or associated computational
methods was something like 1976, and I don't use it much in my research.
Or haven't until now...;-)
