| Version | Published | Release Notes | Action |
|---|---|---|---|
| 3.2.1 | - Stride order minimization was implemented. This improved a07 example speed by 2.7x on the direct solver and 1.5x on the iterative solver.
|
||
| 3.2.0 | - Refreshed examples.
|
||
| 3.1.0 | - Developer guide was out of date with the part1 and part2 workflow.
|
||
| 3.0.8 | Bug Fixes Forgot to commit uv lock file. (4ea4425) Updating base project files. (c01d007) Working on updating project files. (37d6698) |
||
| 3.0.7 | Documentation Moving the developer documentation to the Sphinx site. (edfc1c5)
Bug Fixes Documentation was not properly built before toolbox creation. |
||
| 3.0.4 | Switched documentation to Sphinx-based static site. |
||
| 3.0.3 | Fixing examples that weren't working. |
||
| 3.0.2 | Something is wrong, such that the Examples tab shows "File Not Found". This is an attempt to fix that issue. If it doesn't, I will have to contact MathWorks. |
||
| 3.0.1 | No change to version. Adding an image. |
||
| 3.0.0 | See CHANGELOG.md |
||
| 2.4.0 | Added a function to auto-generate monotonic constraints, monotonicConstraint.m. It should help problem setup creating constraint matrices. |
||
| 2.3.1 | Added readme's for a simple explanation.
|
||
| 2.3.0 | Updated examples.
|
||
| 2.2.5 | Added better documentation of lsqConstrainedAlternative. The documentation is integrated into the MATLAB help system. |
||
| 2.2.2 | Updated direct vs. iterative solver example. |
||
| 2.2.1 | Fixed a problem with one of the examples. |
||
| 2.2.0 | The documentation loads into MATLAB builtin documentation under Supplemental Software. Attached is a toolbox file. |
||
| 2.1.2 | Added a basic getting started file. |
||
| 2.1.1 | Fixed an issue with a missing graph in the documentation. |
||
| 2.1.0 | Had to convert all the documentation and examples to live scripts because File Exchange wasn't displaying the published m files. UGH! |
||
| 2.0.0 | - Added constraints and documentation. This is a major change. The new function is regularizeNdMatrices. See the examples for more information.
|
||
| 1.8.0 | updating description |
||
| 1.7.0 | Just some formatting changes to the description. |
||
| 1.6.0 | Some formatting was messed up on the gridfit example. I had to republish. |
||
| 1.5.0 | more updates to examples. |
||
| 1.4.0 | -Added several examples.
|
||
| 1.3.0 | Small update to the function description. |
||
| 1.2.0 | Added a note about ndgrid format of yGrid. yGrid is in the ndgrid format at not the meshgrid format. There is no analogue of the meshgrid format for higher dimensions. In 2d, ndgrid is the transpose of the meshgrid format. |
||
| 1.1.0 | Fixed a bug I introduced in the last week. |
||
| 1.0.0 | Added a picture. |
