I can't figure out why I am getting NAN and complex numbers returned from intxy. Any suggestions?

17 Jan 2010 MESH2D - Automatic Mesh Generation Generates unstructured triangular meshes for general 2D geometry. Author: Darren Engwirda

I would like to generate a mesh with certain nodes specified on the interior. When I try to do this I end up with areas of my domain that are not filled with elements. For example, I would like node[0.25 0.5] connected to node[0.75 0.5] and the mesh to fill the entire region from [0 0;1 0;1 1;0 1]. The actual meshes I would like to make have more complex node positions.

The following produces a hole in the mesh:

node=[0 0;1 0;1 1;0 1;0.25 0.5;0.75 0.5];
