Download	10 Jul 2014	1.6.0.0	more minor fixes
Download	10 Jul 2014	1.5.0.0	few more minor corrections. All the big calculations are set as single precision currently.
Download	10 Jul 2014	1.4.0.0	I temporarily uploaded a version which used massive arrays. This one is back to normal.
Download	10 Jul 2014	1.3.0.0	This version is faster and uses less memory. It uses the 'stencil' approach: see the comments for details.
Download	29 Jul 2013	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.
