Thread Subject: How to access overridden function?

Is there any way to access on overridden function in Matlab? I have installed the prTools toolbox, which has it's own definition of 'dataset'. There is another definition of 'dataset' in the statistics toolbox - how can I choose which of them I want to use at any particular moment (changing the order of toolboxes in my path is not a solution)?
Thanks

Without changing your path, the only way is to move
(via cd) to the directory in question. The current
directory is always at the top of your search path.

Well, I was thinking about it but there is another problem: when I have already created some objects of one type, and then I want to create an object of this other type, I get an error message:

Cannot redefine class 'dataset' without a call to 'clear classes'.

In other words I am not able to use both types at the same time.

Could you put prTools in a package directory? I haven't done it and I'm
not familiar with prTools, but the general idea would be to put
everything that is part of prTools in a directory called, say,
'+prtools' which is itself in a directory on your path:

   <directory on path>/+prtools/<contents of prTools>

Then you could access the prTools dataset with

  prtools.dataset(...)

I gather from the documentation on packages that this won't work if
prTools has old-style classes (no classdef statement), but it's worth
looking into.
