Re: [Help-gsl] Eigenvalues of Nonsymmetric matrices

[Carl Boettiger]

Hmm, compiles fine for me. not sure what's up, particularly given that
the first example compiles.  Check for typos?  Version of gsl?
compile flags?  I've attached my copy-pasted code, I think this is the
example you are talking about.
