```Hello,

unzipped and placed it in C:\Program Files\GNU Octave
2.1.73\usr\share\octave\2.1.73\m\octave-forge

octave:2> x = rand(1,10);
octave:3> y = rand(1,10);
octave:4>
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
`/usr/share/octave/2.1.73/m/octave-forge/delaunay.m'
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 delaunayn.cc 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.

Hello,

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)) ];
axis([0,1,0,1]);
plot(X,Y,'b;;',x,y,'r*;;');

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,

Saleem
