v0.10.0

Manifolds v0.10.0

Diff since v0.9.20

Changed

• Distributions.jl, RecursiveArrayTools.jl and HybridArrays.jl were moved to weak dependencies to reduce load time and improve extensibility.
• translate_diff, inv_diff and thus apply_diff_group, are available for all the groups with invariant tangent vector storage.
• SpecialEuclidean group now has a different default tangent vector representation, the left-invariant one; to get the old representation pass vectors=HybridTangentRepresentation() to the constructor of SpecialEuclidean.
• adjoint_action takes a direction argument; by default it is LeftAction.
• adjoint_action! is the necessary method to implement in groups with left-invariant tangent vector representation.
• Fixed a few typos in the doc string of the SPD fixed determinant description.
• Random point on the MultinomialSymmetricPositiveDefinite manifold was improved to make it more robust.

Added

• Introduced exp_inv and log_inv based on exp_lie and log_lie. They are invariant to the group operation.
• A tutorial about usage of group-related functionality.

Removed

• Deprecated bindings:
  • ExtrinsicEstimation() (should be replaced with ExtrinsicEstimation(EfficientEstimator())),
  • Symplectic (renamed to SymplecticMatrices),
  • SymplecticMatrix (renamed to SymplecticElement).
  • AbstractEstimationMethod (renamed to AbstractApproximationMethod).
  • VectorBundleVectorTransport (renamed to FiberBundleProductVectorTransport).
  • rand on SymplecticMatrices and SymplecticStiefel no longer accepts hamiltonian_norm as an alias for σ.
  • mean! and median! no longer accept extrinsic_method (should be replaced with e = ExtrinsicEstimation(extrinsic_method)).
• As a result of making Distributions.jl and RecursiveArrayTools.jl weak dependencies the following symbols are no longer exported from Manifolds.jl. Essential functionality is still available but distribution-related features may change in the future without a breaking release.
  • ArrayPartition (RecursiveArrayTools.jl needs to be explicitly imported),
  • ProjectedPointDistribution (not exported),
  • normal_tvector_distribution (not exported),
  • projected_distribution (not exported),
  • uniform_distribution (not exported).
• Ability to create non-real SymplecticStiefel and SymplecticGrassmann manifolds; essential functionality was missing so it was removed until a more developed version is developed.

v0.9.20

Manifolds v0.9.20

Diff since v0.9.19

Added

• implemented parallel transport on the Grassmann manifold with respect to Stiefel representation

Changed

• since now all exp/log/parallel transport are available for all representations of Grassmann,
  these are now also set as defaults, since they are more exact.

• Implement and document parallel transport on Grassmann. (#731) (@kellertuer)
