Re: calling Fortran code from Lisp

Possible, and easy.
I actually have an autogenerated wrapper for all of LAPACK using CFFI:

I have not personally run this on cmucl (only sbcl), but it should be
relatively straightforward.  

There is also MATLISP, which is a higher-level and therefore more
pleasant interface, although I don't know if it includes the
functionality you wnat.  I have added new LAPACK functions to MATLISP in
the past, but it's not an enjoyable activity.
