Simulates the heat equation, with constant heat capacity and thermal conductivity, using GPU (parallel computing toolbox) or CPU (matrix calculations). Includes results from Nvidia titan and i5-2500k @ 4.2 GHz. Any suggestions welcome on speeding up either.

Version Published Release Notes
1.6.0.0

more minor fixes
1.5.0.0

few more minor corrections. All the big calculations are set as single precision currently.

1.4.0.0

I temporarily uploaded a version which used massive arrays. This one is back to normal.
1.3.0.0

This version is faster and uses less memory. It uses the 'stencil' approach: see the comments for details.
1.2.0.0

Was advised by Mathworks that one of the submitted files was not a .m file, so I've re-submitted the zip archive.
