Very nice!

I had to rename vtksurf-0.1.cc to vtksurf.cc and modify the file 
slightly to get it to compile with g++ 3.3.1


$ diff vtksurf-0.1.cc vtksurf-0.3.cc
15c15
< Function to generate a VTK file (fname) of a surface from a two 
dimensional matrix.

There are also a couple of changes that I think can be made to make it 
more portable, i.e. less version dependent


$ diff vtksurf-0.3.cc vtksurf-0.4.cc
7c7
< #include "octave-2.1.50/octave/oct.h"

---

$ diff Makefile-old Makefile
3c3
< 	mkoctfile-2.1.50 vtksurf.cc -L$(HOME)/lib -I$(HOME)/include 
-lstdc++-3-libc6.2-2-2.10.0
