uso ubuntu 7.04 ed ho appena installato octave forge con Octave, version 2.9.9 (x86_64-pc-linux-gnu),e volevo usare la funzione delaunay copiando dal sito(e da help delaunay) ma da errore:
Codice: Seleziona tutto
x=rand(1,10);
octave:6> y=rand(size(x));
octave:7> delaunay(x,y)
qhull internal error (qh_qhull): temporary sets not empty (2)
While executing: | qhull d Qt Qbb Qc
Options selected for Qhull 2003.1 2003/12/30:
delaunay Qtriangulate Qbbound-last Qcoplanar-keep _pre-merge

_one-merge 9.2e-15 Visible-distance 2.6e-15 U-coplanar-distance 2.6e-15
Width-outside 5.3e-15 _wide-facet 1.6e-14
Last point added to hull was p3.
