| 
| --------------------------
| clear all
| clf
| load csd_data
| meshc (X,Y,Z);
| r = axis;
| r(1) = min (min (X));
| r(2) = max (max (X));
| axis (r);
| view(20,25);
| --------------------------

What is csd_data?  If it is a large file, please don't post it to the
list.  If it is possible to duplicate the problem with arbitrary data,
give us a simple function to generate data that can be used to
demonstrate the problem.  If the problem is dependent on specific data
and the file is large, please post it to a web site if possible and
give us a link.
