Hi, 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). If anybody could share his/her experience, I would be very grateful. Some (soft) requirements: - It should be implemented in "pure" Common Lisp. Preferably no wrappers for libraries implemented in other languages. - Preferably sequential, but parallel implementations may also be fine. - Focus on performance (incl. low-level type declarations, for example). - Preferred platform is LispWorks, but other Common Lisp implementations are also fine. Portability is not a high priority. Thanks a lot in advance, Pascal -- Pascal Costanza, ExaScience Lab, Intel Belgium
