platform dependency?

["michael ege" <michaelege@web.de>]

Hi,
I'am using Jama on a NT System and on an Unix Server (Sun Solaris).
The problem is:
We do for example a rank calculation of a 250 dimensional quadratic matrix.
Thereby we get different results, the calculation on the NT yields full rank
and the one on the Unix machine rank 1. The bigger eigenvalues of this
matrix nearly the same. But there are negativ eigenvalues on the Unix
calculation against no negativ eigenvalues on the NT OS.
Could the Jama code be platform depend?

Thanks,
Michael Ege
