feature or bug?

[Bertrand Roessli]

Hello,

it looks like the function 'griddata' does not work in
octave 3.1.54. Should it be so?

[xp,yp,zp]=griddata(data(:,1),data(:,2),data(:,3),a,b);

error: __delaunayn__: not available in this version of Octave

Thanks,

Bertrand

Hello Bertrand,

where did you get your octave from? It seems you don't have
__delaunayn__ available. You could check with:
which __delaunayn__ at the octave prompt.

This is what i get:
octave-3.0.3.exe:1> which __delaunayn__
__delaunayn__ is the dynamically-linked function from the file
C:\Programme\Octave\libexec\octave\3.0.3\oct\i686-pc-msdosmsvc\__delaunayn__.oct

It could be your octave was not compiled with qhull support, but without
more information this difficult to tell.

Kai

did you compile Octave from sources?
__delaunayn__ requires the qhull library,
if qhull was not detected at configure time
__delaunayn__.oct was not built, hence the error.

Yes you are right. Qhull was not installed.

Thanks,

Bertrand
