I've been slowly working on writing a lisp replacement for noweb because I'd like to continue developing the library using literate programming. If any of you want to use it and have patches, just submit them as patches on the lisp files and I'll worry about the literate source.</div>

Hi,<br>
<br>
I am looking for a Common Lisp library that provides some essential mathematical matrix/vector operations. There seem to be a couple of offerings, but it seems hard to determine in what kind of state they are (without essentially trying them all one by one).<br>
<br>
If anybody could share his/her experience, I would be very grateful.<br>
<br>
Some (soft) requirements:<br>
- It should be implemented in "pure" Common Lisp. Preferably no wrappers for libraries implemented in other languages.<br>
- Preferably sequential, but parallel implementations may also be fine.<br>
- Focus on performance (incl. low-level type declarations, for example).<br>
- Preferred platform is LispWorks, but other Common Lisp implementations are also fine. Portability is not a high priority.<br>
<br>
<br>
Thanks a lot in advance,<br>
Pascal<br>
