My PDE toolbox Femlisp (<http://www.femlisp.org>) contains such code (basic
matrix arithmetic and Gauss elimination with pivoting) in the directory
"femlisp:src;matlisp;". It does matrix class generation and method
compilation adapted to the matrix element type at runtime and should
therefore be not much slower than ordinary LAPACK. However, the cache- and
architecture-optimized ATLAS routines (which can be used from CL with
Matlisp, see <http://matlisp.sourceforge.net/>) are much faster for
medium-sized and large matrices.
Yours, Nicolas.
