CCL:eigenvalues & eigenvectors



David,
Have a look at LABPACK http://www.netlib.org/lapack/ and its precursor EISPACK http://www.netlib.org/eispack/.  The latter  was developed at Argonne  while the former is an OAk Ridge NL product that  incorporates Eispack equivalent routines and much more.  It also has its own search  engine to help identify suitable subroutines. The program are written in Fortran 77

Dear CCL,
 
Does anyone have or know of freeware that can
compute the eigenvalues and eigenvectors of a
real symmetric matrix (e.g a Hessian, but not
necessarily a Hessian)?  I'd be content to run
under either Windows or Linux.
 
Thank you,
David Anick PhD MD
