The problem comes from the fact that load() can either load in lisp code
or Maxima code. To decide which it's getting, it seems to check for the
file extension, defaulting to lisp. So the errors you get come from it
trying to read weightingmatrix.mxs as lisp, which it isn't!
A solution/workaround is to use batchload() instead, which seems to work
the same, but assume that you're giving it Maxima code.
