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...;-) rgb
