function varargout = patchGraph(nodes, edges, faces) %#ok<INUSL>
%PATCHGRAPH Transform 3D graph (mesh) into a patch handle.
%
% [PX, PY, PZ] = PATCHGRAPH(NODES, EDGES, FACES)
% Transform the graph defined as a set of nodes, edges and faces in a
% patch which can be drawn usind matlab function 'patch'.
% The result is a set of 3 array of size [NV*NF], with NV being the
% number of vertices per face, and NF being the total number of faces.
% each array contains one coordinate of vertices of each patch.
