Hi Matlab shows following error. How to change this?

??? Input argument "y" is undefined.

Error in ==> delaunay at 38
if equal(size(x),size(y))

Error in ==> Beam3D at 16
t=delaunay(p); % connectivity

Hi, MATLAB calls a mistake in Beam3d.m at 16 line:
Needs at least 2 inputs.

Error in ==> Beam3D at 16
t=delaunay(p); % connectivity

how to change it?
