I don't think that Matlab preserves the case of the options set, but
you do have to be able to set and query in a case insensitive way.


I think it always uses "TolX".  But unless it is expected that users
will access the fields directory with struct indexing operations
then I don't see why the internal names have to use StudlyCaps.  But
if it is necessary to be able to do things like

  opts = optimget ();
  opts.TolX = foobar;

  fsolve (..., opts);

(and I guess I would expect there to be some code out there that works
this way) then I guess we are stuck with the exact names they choose.
