Thanks for your help so far. I have made some progress. I downloaded (octave-forge link), 
unzipped and placed it in C:\Program Files\GNU Octave 

octave:2> x = rand(1,10);
octave:3> y = rand(1,10);
octave:4> T = delaunay(x,y);
error: `delaunayn' undefined near line 51 column 13
error: evaluating assignment expression near line 51, column 11
error: evaluating if command near line 50, column 5
error: evaluating if command near line 49, column 3
error: called from `delaunay' in file 
error: evaluating assignment expression near line 4, column 3

It does find delaunay.m as the file is there. But is fails to locate 
delaunayn.m. That folder does contain a which is the c++ source 
code. I presume the problem is that this needs to be compiled -- I am wondering 
if there is a place I can download the compiled version for windows.

Thanks for your help,

Just downloaded Octave for Windows version 2,1.73

          x = rand(1,10);
          y = rand(size(x));
          T = delaunay(x,y);
          X = [ x(T(:,1)); x(T(:,2)); x(T(:,3)); x(T(:,1)) ];
          Y = [ y(T(:,1)); y(T(:,2)); y(T(:,3)); y(T(:,1)) ];

error: `delaunay' undefined near line 3 column 5
error: evaluating assignment expression near line 3, column 3

Any ideas on how I could fix this would be greatly appreciated. Thanks,
