regularizeNd
regularizeNd
Creates a gridded lookup table from scattered data in n dimensions.
regularizeNd is function written in MATLAB that extends functionality of RegularizeData3d from 2-D input to n-D input. More background can be found here: https://mathformeremortals.wordpress.com/2013/01/29/introduction-to-regularizing-with-2d-data-part-1-of-3/
The basic idea is that a lookup table is fitted to the scattered data with a required level of smoothness. The smoothness parameter trades between goodness of fit and smoothness of the curve (1-D), surface (2-D), or hypersurface (n-D).

Version | Published | Release Notes | |
---|---|---|---|
2.4.0 | Added a function to auto-generate monotonic constraints, monotonicConstraint.m. It should help problem setup creating constraint matrices. |
|
|

|
|
|
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 | Had to convert all the documentation and examples to live scripts because File Exchange wasn't displaying the published m files. UGH! |
|
|
2.0 | - Added constraints and documentation. This is a major change. The new function is regularizeNdMatrices. See the examples for more information.
