Hello Ray,

Yes, I would be willing to donate it.  The question is, if the benefit is
in a suitable relation to the work to do.  In my eyes, a reasonable work
program for improving Matlisp would be the following:

1. One should use the FL.MATLISP matrix structures (automatically
   generated) for Matlisp.  Printing and read-macro [] should be taken from
   Matlisp.

2. One should automate Matlisp's BLAS interface.  Something like (get-blas
   'daxpy) should make the Fortran daxpy routine available.

3. Also Matlisp's methods for BLAS and LAPACK generic functions which
   interface the Fortran routines should be automatically generated
   whenever possible, maybe following the route I took in Femlisp.  It
   would be nice if one could also extract documentation.
   Anyway, this is the hard part.  I am not sure if it is doable without
   a lot of work.

4. Extensions like matrix slices, etc, allowing easy translation of Matlab
   code should be provided.

This program is nontrivial, and at the moment I cannot afford to work on
it, since I am searching for a job.

It looks as if there are only very few people actually using Matlisp.
Considering this, there may be other places where spending CL programmer
time is more fruitful at the moment.

Yours, Nicolas.
