| Version | Published | Release Notes | Action |
|---|---|---|---|
| 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. |
