Comsol/Matlab code and data used in finding optimal Young's moduli

Here is the code and data files used to generate Figure 9. Comsol Multiphysics 3.5 and matlab 7.4.0 (2007a) were used.

To use this, first start Comsol. Within Comsol, "File : Client/server/MATLAB : connect to MATLAB". A matlab window opens up. In the matlab window, go to the proper directory and execute file fit4Davg.m.

The top routine fit4Davg.m . reads in the data files sidemedia.txt and centermedia.txt , which are the averaged measured displacement on a lattice. It uses matlab routine lsqcurvefit with the error function CenterSide4Dmkh.m to optimize the Young's moduli; this routine uses center4Dmkh.m and Side4Dmkh.m

YM.zip is a zip file with the code and data files.
