Notes on release changes and ongoing development


v0.5.2

  • change derivative matrix function call to Γ(m::Int, order::Int)
  • remove Matrix Depot as dependency

v0.5.0

  • Significant performance gain in "setupRegularizationProblem" by switching from GSVD to QR factorization approach
  • Update documentation
  • Update tests to be independent of random number generation
  • Update Project and Manifest to be current. Added CSV and DataFrames as deps for unit tests
  • Explicitly account for the unregularized component of x which is not affected by the regularization scheme (fix for issue #7 raised by Jonathan Stickel). Note that the bug/issue affected solutions for very larger regularization parameters, but had no/neglible effect on calculations near the optimal solution for regularization.
  • Update code for smoothing matrix generation (base on example in issue #7 contributed by Jonathan Stickel). The updated code also directly allows computation of arbitrary order of the smoothing matrix.
  • Added smoothing example from issue #7 to examples folder

v0.4.1

  • Minor release associated with julia 1.6.0
  • Update Project and Manifest
  • Make tests of invert function resilient against changes in random number generator
  • Change order in scattering example to 2

v0.4.0

  • Add high-level API invert function to simplify notation

v0.3.1

  • Add memoization
  • Merge CompatHelper: add new compat entry for "Memoize" at version "0.4"
  • Fix various bugs related to non-square matrices

v0.3.0

  • Add abstract interface to generate design matrix from a forward model.
  • Add documentation and examples how to use the interface
  • Add fallback in solve function in case cholesky factorization fails.
  • Fix bug when creating L matrix for non-square design matrices.

v0.2.0

  • Add constraint minimization solver to enfore upper and lower bound for some problems.
  • Add documentation.

v0.1.1

  • Fix standard form conversion error. Solution is now based on generalized SVD.
  • Touch up documentation.
  • RegularizationTools is now part of the general registry

v0.1.0

  • Initial Release
