Hallo,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to solve the following problem. I need to get eigenvectors of a matrix. I know that there are many subroutines for that in linear algebra packages, for instance in Lapack there is DSPEV, but they all givenormalizedeigenvectors, while I need the "original"unnormalizedones. I will very appreciate any idea/point how one can solve this using a standart library/subroutine in C or fortran (to embed it in a code written in C/frotran).

Many thanks!

Best regards,

Evgeniy
