COMMUNITY PROJECT MATLAB FILES

The following MATLAB files were written by the class of Fall 2012 as a community project to help students all over the world develop their own programs for macromechanical lamina and laminate analysis.  Use them as you please and give us any feedback at kaw@usf.edu.  Do you want some other files built?

Each of the files is written as a function file.  A testing file is also given to check its use and output.
