| I never wrote num2cell for 2.1.x and so I don't think it will compile.

| 
| 
http://cvs.sourceforge.net/viewcvs.py/octave/octave-forge/main/cell/Attic/num2cell.cc?rev=1.6&view=auto
| 
| Maybe if you replace "octave_idx_type" with "int" it might compile on 
| 2.1.x though I haven't tried. Note the code is in C++ and must be 
| compiled with "mkoctfile num2cell.cc" before being used..

I thnik the bigger problem is that the OP is trying to run the C++
code as a .m file instead of saving it as a .cc file and running
mkoctfile on that.
