Thread Subject: How to get 2D Triangular Mesh

Here is my problem. I want to mesh 1x1 square domain using some
unstructured mesh technique. I'm trying to do it using triangular
elements. The problem is I haven't played much with matlab and hence
facing difficulties doing this. I tried to play with 'delaunay'
command and ended up with some triangles over the region. However for
my problem still I need to vertex locations of each triangle which I
don't know yet(to find the location of triangle to apply BCs). Also
I'm not clear with the out put of this command whether there is any
order for triangles or not. I appreciate if you could help me to get
this done. I don't mind if you have any other better mesh generator
which gives the same(able to run in matlab).
Thanks!

Hi Dulp,

as I have no good idea I searched ..
