Hi all, I'm new with Matlab. Is there a function which can replace delaunayn? I need to transform a code from Matlab to C++ through Matlab coder, but this function is not supported. I don't striclty need a function which follows the Delaunayn rules, but it can also provides a general triangulation between nodes.

Thank You all

Matlab uses qhull for the calculation of delaunayn. qhull is a library written in C, see here: http://www.qhull.org/ So it should be possible to rewrite the code in pure C or C++ directly or to call a Mex function.
