Miquel,

doesn't work very well ...

I have this windows package version of octave, =
octave-forge-2.1.50-windows.
It does have delaunay.m and delaunay3.m. Now I tried the example in the
online help of delaunay and get

>>           x =3D rand(1,10);
>>           y =3D rand(size(x));
>>           T =3D delaunay(x,y);
error: `delaunayn' undefined near line 51 column 13

so delaunay and delaunay3 rely on the presence delaunayn, which is not
there.

I downloaded the latest ocatave-forge-2004.11.16.tar.tgz and explored a
little to find that delaunayn is a C++ source (loadable function?).
delaunayn.cc requires to #include qhull_a.h, which is not part of the
sourceforge tgz I downloaded.

Seems to get hairy for a person who never compiled a user-defined =
function
before.
And where do I get the qhull sources?
And do I need to get gcc installed in my cygwin environment (which came =
with
the octave-2.1.50a-inst.exe?

Am I correct, or is the world actually a little simpler than this?


Norbert

this function is part of Octave-Forge. You can find it at,
