||
| 1.19.0 | Add regularization to make quadprog more robust. This is important change for those who use QUADPROG as engine. |
||
| 1.18.0 | Fix the bug when starting knots are provided |
||
| 1.16.0 | Fix the bug for continuous regularization |
||
| 1.15.0 | Fix a small bug (eigs with 'sa' option requires true symmetric matrix, which is now always the case by symmetrizing) |
||
| 1.14.0 | A more robust conversion in pp form is implemented |
||
| 1.13.0 | Remove some redundant code, modify test program |
||
| 1.12.0 | New feature: Periodic spline |
||
| 1.11.0 | fix a bug with parsing k and nknots
|
||
| 1.10.0 | fixed small bug when calling QP engine minqdef |
||
| 1.9.0 | Correct a bug in UpdateConstraints that did not update the knot positions. Precasting data to double. Update more frequently the scaling matrix. Reduce the Lagrange's tolerance to detect active set of QPC solver |
||
| 1.8.0 | Singular constraints will issue a warning (instead of an error). Refine the Gauss-Newton direction. Fix few minor bugs. |
||
| 1.7.0 | Change the description. |
||
| 1.6.0 | Correct another bug in the Jacobian calculation (constrained case) |
||
| 1.5.0 | Point-wise constraints. Discover an error of the Jacobian formula in [Schutze/Schwetlick 97] paper, modify the calculation accordingly. This concern only the constrained fitting. |
||
| 1.4.0 | A major enhancement with shape preserving splines |
||
| 1.3.0 | Change title and description |
||
| 1.2.0 | Remove NaN data before fitting, change TRY/CATCH ME syntax for better compatibility (tested under 2006B), estimate automatic of the noise standard deviation |
||
| 1.1.0 | Update description, more options added to control the fit, discrete regularization |
||
| 1.0.0 |
