If you have suggestions on what to say, please send them here and I'll
try to get them incorporated.

Ok.  I'll see if I can change this.  Perhaps Tunc can do this.  I've
never touched the matlisp home page so I don't know how.

Isn't this the standard BSD license?  Tunc wrote that.

    rif> 4.  Is it a bug that (at least under CMUCL) mref is not setf-able?  i.e.:

    rif> * (setf (matrix-ref a 0 1) 3)
    rif> 3.0d0
    rif> * (setf (mref a 0 1) 4)
    rif> Warning: This function is undefined:
    rif>   (SETF MREF)

Since this is defined in compat.lisp, I suspect it was originally
called mref, but was later changed to matrix-ref.  I would say mref is
deprecated; use matrix-ref.
