.. using either 'old' or 'new' (undocumented) syntax.

New:

  classdef mydatabase < database
  end

>> z = mydatabase
??? The specifed superclass 'database' is invalid or
contains a parse error.

Old:

  function[obj] = mydatabase(varargin)
  obj = class(struct([]),'mydatabase',database(varargin
{:}));

>> e = mydatabase(<connection parameters>)
??? Error using ==> class
Can't redefine class mydatabase without a call to clear
classes.

(I have cleared classes).

Any suggestions? (Except for contacting TMW :))

Thanks!

Problem solved: the derived class is instantiated alright,
it's 'display' that triggers an error!
