I am in terrible need of Pascal code that finds the eigenvalues and eigenvectors of a general real matrix. If someone out there has such a code, would you please let me know? I got the rg routine from statlib@temper.stat.cmu.edu, but unfortunately for me the code is in FORTRAN.

A trivial suggestion. Have you looked at Borland's Turbo Pascal Numerical Toolbox. ...................................................................

( 40 West 20th st. NY ). (Probably available at your local good bookstore but the publishers have the routine on disk.) I use the "C" version and it is extremely good. A few little bugs like the way they sometimes address arrays (nothing I have found that would cause the programme to crash though). It has a suite of programmes for eigensystems. The methods are very well thought out and go far beyond the ususal simple approaches, so that the performance is optimum. --------------------------------------------------------------------- email to UUCP: uunet!mimsy!{arinc,fe2o3}!vk2bea!michael _ _ _ _ Amateur | VK2BEA (Australia) ' ) ) ) / // Radio | G4NYV (United Kingdom) / / / o _. /_ __. _ // Stations| NV3Z (United States) / ' (_<_(__/ /_(_/|_</_</_ Michael Katzmann Broadcast Sports Technology. 2135 Espey Ct. #4 Crofton Md. 21114 USA Ph: +1 301 721 5151
