| Version | Published | Release Notes | Action |
|---|---|---|---|
| 2.3.0 | BSXFUN is no longer used (version thus must be >= R2017) |
||
| 2.2.1 | verLessThan('matlab','9.2'); instead of verLessThan('matlab','9.1'); |
||
| 2.2.0 | - fixed bug in isstruct(varargin{end-1})
|
||
| 2.1.4 | updated links |
||
| 2.1.3 | updated links |
||
| 2.1.2 | updated links |
||
| 2.1.1 | . |
||
| 2.1.0 | minor updates: 1) use narginchk, 2) two warning messages slightly modified |
||
| 2.0.0 | minor update: 1) use narginchk, 2) some warning messages slightly modified |
||
| 1.37.0 | I noticed a minor error in one comment |
||
| 1.36.0 | . |
||
| 1.35.0 | . |
||
| 1.34.0 | Some modifications in the help text |
||
| 1.33.0 | To simplify the syntax, the termination parameters are now in a structure (OPTIONS). |
||
| 1.32.0 | Numerical adjustment in the leverage (for robust smoothing) in the case of unequal spacing increments. |
||
| 1.31.0 | SMOOTHN, by default, assumes that the spacing increments are constant and equal in all the directions (i.e. dx = dy = dz = ...). Spacing increments that differ from one direction to the other can now be used (enter "help smoothn" for details). |
||
| 1.30.0 | There was a non negligible bug in the new SMOOTHN function:
|
||
| 1.28.0 | Update of the help text |
||
| 1.27.0 | A minor bug in the "Initial Guess" criterion has been removed |
||
| 1.26.0 | A bug was present when dealing with complex numbers |
||
| 1.25.0 | A small bug was present in the subfunction InitialGuess (Thank you Jonathan!) |
||
| 1.24.0 | One bug has been fixed. |
||
| 1.23.0 | SMOOTHN now works with multicomponent data (e.g. 3D vector fields) by using cell arrays. See the help text for details. |
||
| 1.22.0 | DCTN and IDCTN are now included in SMOOTHN |
||
| 1.21.0 | some typos |
||
| 1.20.0 | 3 optional weighting functions |
||
| 1.19.0 | 3 optional weighting functions |
||
| 1.12.0 | minor modifications: mlint messages removed |
||
| 1.11.0 | Some options have been removed/added |
||
| 1.10.0 | fix a minor bug with the warning messages |
||
| 1.9.0 | Minor modification in the relaxation factor |
||
| 1.8.0 | A minor bug in error(nargchk(...)) |
||
| 1.7.0 | Gamma was undefined when "isauto" variable was false. |
||
| 1.6.0 | The link to the manuscript has been modified. |
||
| 1.5.0 | A bug has been reported with a smoothness parameter input. Thank you B.S. |
||
| 1.3.0 | Very much faster now with weighted/missing data:
|
||
| 1.2.0 | The "upsample" option has been removed |
||
| 1.1.0 | An example has been added |
||
| 1.0.0 |
