Hi,

I want to compute the dominant eigenvalue of some non-symmetric 
matrices, so I was happy to find out that the numeric bindings library 
provides an interface to some lapack routines. I chose the gees routine, 
but now I got stuck with the following error:  
   
error: no match for call to 
`(boost::numeric::bindings::lapack::detail::Gees<1>) (char, 
boost::numeric::ublas::matrix<double, 
boost::numeric::ublas::column_major, 
boost::numeric::ublas::unbounded_array<double, std::allocator<double> > 
 >&, boost::numeric::ublas::vector<double, 
boost::numeric::ublas::unbounded_array<double, std::allocator<double> > 
 >&, boost::numeric::ublas::vector<double, 
boost::numeric::ublas::unbounded_array<double, std::allocator<double> > 
 >&, double*&)'

Can anybody give me some indication about the error? Did I declare 
"workspace" with the proper type? Below I attached the code.

Thanks in advance for any help!
