## Benchmark test of Octave on Windows.

 From: Ole Jacob Hagen Subject: Benchmark test of Octave on Windows. Date: Mon, 24 Jan 2005 13:01:29 +0100 User-agent: Mozilla Thunderbird 1.0 (Windows/20041206)

```Hi.

I have managed to link Octave with ATLAS on Windows.
Octave is compiled with MinGW, and atlas is built with Cygwin.

Cheers,

Ole J.

Here is the results from my benchmark test on an AMD xp 2400 +, with 512 MB RAM where Octave is linked with ATLAS.
