MatLisp
MatLisp is a BLAS and LAPACK linear algebra library wrapper which makes their features accessible through a set of CLOS classes.

Source code is available at the project site. The system currently runs under CMUCL and SBCL, and it will be ported to CLISP as soon as some issues related to C compatible specialized arrays are dealt with.

The MatLisp matrix library was originally developed by Raymond Toy and Tunc Simsek, and officially announced in April 2000. It is now maintained by Tunc Simsek.

Some of MarkHoemmen's ideas about a second generation implementation. See also GSLL, FEMLISP, NLISP for linear algebra in Lisp.
