[pro] Matrix operations...

[Thomas M. Hermann]

Pascal,

I have a library that is essentially a common lisp implementation of the
BLAS. So, it is just the low level routines, nothing that you would find in
the LAPACK. It is sequential. It works in any lisp implementation. I
originally developed it using SBCL, but there is nothing SBCL specific in
the code. I've compiled it using LispWorks and all of the unit tests pass.
All of my development is now in LispWorks, so that is the platform that any
further development will occur on.

There is no focus on performance whatsoever. In fact, I can almost guarantee
that the performance is not good. My intent at this stage of development was
to focus on correctness and the API, then focus on performance. I'd be happy
to work with you on this.

I have a working draft of the documentation that I can send you. If you are
interested in the code, I think the best way to share it would be through
github.

Please let me know if you are interested and I will email you the
documentation directly.

Best regards,

~ Tom
