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...;-)
