Hi --

As far as I know, none of the original developers of Jama, including me,
are actively working on the package today.  Execution speed was not an
important design goal for Jama.  At the time, Java speed was so much
slower than Fortran, C, or machine optimized BLAS, that we had no
intention of competing in that arena.

I was not aware of Colt until your post.  Thanks for bringing it to my
attention.  According to

 
http://dsd.lbl.gov/~hoschek/colt/api/cern/colt/matrix/linalg/package-sum
mary.html#Overview

Colt borrows many algorithmic ideas from Jama, but pays more attention
to performance.  Because of that, I expect Colt is faster than Jama, but
I don't know of any quantitative results.

Hi,

I'd like to know what's the current status of Jama regarding:
* bug fixes;
* support on JDK6
* performance on JDK6

How do you compare Jama and Colt?
Any advantage on using Jama over the version embedded in Colt?

Thanks
