matrix package with Ada
in [ADA]

From: fitta on 10 Jul 2010 09:25 Hi, being new to Ada I'm looking for a matrix package that can compute eigenvalues and eigenvectors. I understand that Ada 05 can only do this for symmetric matrices. I read that there was one package --- Ada 95 matrix package that was developed at Drexel University. It is supposed to be located at: http://dflwww.ece.drexel.edu/ but the link is dead. A search on the web has directed me to this site: http://www.taygeta.com/ada.html but the compressed file for Ada 95 matrix package is corrupted. Does anyone know where I can find the above-mentioned package? And are there other alternatives or other packages? Thanks.
From: MRE on 10 Jul 2010 09:46 Hi Fitta, downloading the packages from http://www.taygeta.com/ada.html and decompressing worked without a problem for me. Everything compiled nicely and works. Maybe you could try it again?

From: fitta on 10 Jul 2010 11:42 Thanks a lot. I could unzip it now. I have been using PeaZip to unzip the package and it wasn't working. I've tried with 7-zip and the decompression went fine. Thanks for letting me know---I had blind faith in PeaZip! So I see: Ada 95 Matrix Math Package Version 1.01 First Release, August 1996 Current Release, September 1996 and also that a to-do for this package remains: implement eigenvectors/ eigenvalues, singular value decomposition, and inverses for complex matrices. I haven't try the package yet but I'll hope it'll work for a real non- symmetric matrix. Thanks a lot again.
