[Q:] partial differentiation of a surface

Dear netters.
May be you can help with the following problem:
 
A measurement yields a set of data representing a 3-dimensional
surface over an 300 x 80 area.

Now we want to partial differentiate this surface and plot
the result. This should not only be possible in the direction
of the main axes (x, y) but although in the direction of
specified angles (e.g. 45 ). 
 
My questions is:
 
 - How can we do this? Are there any existing programmes or
   add-ons to existing programmes?
 

If you can help, please email to: 
 
ralf.oestereich at chemie.uni-regensburg.de
 
 
In the case of general interest, I will sum up and post
the results to this newsgroup.

Thank you very much in advance!

 
  Best regards, 

  R. Oestereich
