[Help-gsl] about sorting eigenvalues

[Wu Degang]

Hi,

I have a real symmetric matrix and use gsl_eigen_symm to compute the 
eigenvalues. After that I need to sort the eigenvalues, but I find in 
the manual gsl_eigen_symmv_sort, which sorts the eigenvalues as well as 
the eigenvectors. I just need to sort the eigenvalues. What function 
should I use?

regards,
