Thank you for the report, I will fix the examples when I have time... This 
week-end hopefully...

All parameters are quite stupid, I never tested this file before, I will 
explain why it does not work at all, when I will fixed it.

Medit does not manage very well meshes of hexahedra, so consider using OpenDx, 
or the following command:
        mesh T = tetrahedrize(M);
And then save your data using the mesh T which is built of tetrahedra and then 
convinient to Medit. [I know the doc should mension all this, but time is 
very difficult to find :-(]

Best regards,
Stephane.
