Note 0: These programs are no warranty. Use these programs with your own risk. The author cannot be responsible for any trouble caused by the software.

Note 1: Rules of naming (with some exceptions) Executable without arguments: All character of the file name are lower wase (ex: ulink_example.m) Subroutines (need arguments): Contains upper case character (ex: PrintLinkName.m)

Note 2: Matlab for Linux It works at the authors envoriment Vine Linux2.6 + Matlab ver.6.5.

Note 3: If you get unusual 3D graphics Please try the following command. It might work... set(0,'DefaultFigureRenderer','zbuffer')
