Comment (by aric):

 I see I designed the function so the third positional argument is for
 the M matrix of the generalized eigenproblem. So you'll have to specify
 the "which" parameter as a keyword.

 {{{
 def eigen_symmetric(A,k=6,M=None,ncv=None,which='LM',maxiter=None,tol=0,
 return_eigenvectors=True):
 }}}

 Perhaps the order should be changed.  This discussion could take place
 over on #231.
