Re: [Help-gsl] Eigenvalues of Nonsymmetric matrices

[Carl Boettiger]

Hmm, could be it.  I'm using gsl 1.12 (on a ubuntu linux machine).  I
believe 1.13 is the current release, so the example code may not be
written for 1.8.

Perhaps someone else on a Windows machine has some hints on getting
you upgraded.  I think there's been some threads to that effect
before.  Running in Cygwin (or virtualbox linux, nicer, easier
interface but more ambitious setup) might be options.
