[Help-gsl] Eigenvalues of Nonsymmetric matrices

[Chris Gast]

Hello,

I am having trouble computing eigenvalues of nonsymmetric matrices.  I'm
using Code::Blocks 8.02, with the GCC compiler.

When compiling my own project, I get the same error as when I try to compile
the second example at this location:
http://www.gnu.org/software/gsl/manual/html_node/Eigenvalue-and-Eigenvector-Examples.html

(The Vandermonde matrix)

Upon compilation I get an error telling me that
"gsl_eigen_nonsymmv_workspace was not declared in this scope".  I have gone
through the gsl_eigen.h file, and I can see that the struct exists for
gsl_eigen_nonsymmv_workspace, just as it does for gsl_symmv_workspace.  (The
first example on that same page compiles and runs successfully.)

Has anyone run into this problem before?  Know how to fix it?  Thanks for
your help.

Chris Gast
