Notes

In this release the spline representation (the array of spline coefficients) has been changed according to PPoly/NdPPoly. See SciPy PPoly and NdPPoly documentation for details.

v0.11.0 (28.03.2020)

  • Internal re-design SplinePPForm and NdGridSplinePPForm classes #17:
    • Remove shape and axis properties and reshaping data in these classes
    • NdGridSplinePPForm coefficients array for 1D grid now is 1-d instead of 2-d
  • Refactoring the code and decrease memory consumption
  • Add overload type-hints for csaps function signatures

v0.10.1 (19.03.2020)

  • Fix call of numpy.pad function for numpy <1.17 #15

v0.10.0 (18.02.2020)

  • Significant performance improvements for make/evaluate splines and memory consumption optimization
  • Change format for storing spline coefficients (reshape coeffs array) to improve performance
  • Add shape property to SplinePPForm/NdGridSplinePPForm and axis property to SplinePPForm
  • Fix issues with the smoothing factor in nd-grid case: inverted ordering and unnable to use 0.0 value
  • Update documentation

v0.9.0 (21.01.2020)

  • Drop support of Python 3.5
  • weights, smooth and axis arguments in csaps function are keyword-only now
  • UnivariateCubicSmoothingSpline and MultivariateCubicSmoothingSpline classes are deprecated and will be removed in 1.0.0 version. Use CubicSmoothingSpline instead.

v0.8.0 (13.01.2020)

  • Add csaps function that can be used as the main API
  • Refactor the internal structure of the package
  • Add the documentation

Attention

This is the last version that supports Python 3.5. The next versions will support Python 3.6 or above.

v0.7.0 (19.09.2019)

  • Add Generic-based type-hints and mypy-compatibility

v0.6.1 (13.09.2019)

  • A slight refactoring and extra data copies removing

  • Add "axis" parameter for univariate/multivariate cases

v0.5.0 (10.06.2019)

  • Reorganize the project to package-based structure
  • Add the interface class for all smoothing spline classes

v0.4.2 (07.09.2019)

  • FIX: "smooth" value is 0.0 was not used

v0.4.1 (30.05.2019)

  • First PyPI release
