[Help-gsl] Eigen solution of non-symmetric tridiagonal

[Dr. Mehmet SAHIN]

Dear Sir/Madam,
We try to find eigenvalues and eigenvectors of a non-symmetric 
tridiagonal matrix. But we have not found any solution in the GSL 
subroutines. How can we use the GSL subroutines to solve eigenvalues of 
a nonsymmetric tridiagonal marix?
Our real matrix T has the property that the products of pairs of 
offdiagonals T(i,i+1)*T(i+1,i) are all positive. Which subroutine(s) we 
should use? Could you help us about solving this problem?

Sincerely,
