Published by github-actions[bot] about 1 year ago

ManifoldsBase v1.0.0

Diff since v0.15.24

Changed

We implemented the following breaking changes.

to avoid logical ambiguities to the forthcoming LieGroups.jl, the “fusing” variant exp(M, p, X, t) has been moved to its own name exp_fused(M, p, X, t) and similarly exp!(M, q, p, X, t) has been moved to its own name exp_fused!(M, q, p, X, t). Note that the new exp_fused! method is not exported and by default falls back to calling exp! with t*X. Actions to take
- if you just implemented an own exp(M, p, X) or exp!(M, q, p, X) everything works as before.
- if you implemented a fused variant exp!(M, q, p, X, t) you have to adapt two things
- move that implementation to ManifoldsBase.exp_fused!(M, q, p, X, t)
- Implement the default exp!(M, q, p, X) = ManifoldBase.exp_fused!(M, q, p, one(eltype(p)), X), or an own specific implementation for the non-fused variant.
Similar to exp, the “fusing” variant retract(M, p, X, t, m) has been moved to its own name retract_fused(M, p, X, t, m) and similarly retract!(M, q, p, X, t, m) has been moved to its own name retract_fused!(M, q, p, X, t, m). Note that the new retract_fused! method is not exported and by default falls back to calling retract! with t*X. Actions to take
- if you just implemented an own retract(M, p, X, m) or retract!(M, q, p, X, m) everything works as before.
- if you implemented a fused variant retract!(M, q, p, X, t) you have to adapt two things
- move that implementation to ManifoldsBase.retract_fused!(M, q, p, X, t, m)
- Implement the default retract!(M, q, p, X, m) = ManifoldBase.retract_fused!(M, q, p, one(eltype(p)), X), or an own specific implementation for the non-fused variant.
the TVector type has been renamed to AbstractTangentVector
the CoTVector type has been renamed to AbstractCotangentVector

Removed

parallel_transport_along(M, p, X, c), vector_transport_along(M, p, X, c, m) as well as their mutating variants are removed from the API for now. It was never specified how to actually specify a curve c and the method was only implemented for Euclidean in Manifolds.jl, where it is the identity.

Diff since v0.15.23

Added

extended support for allocate_on with ArrayPartition.

Merged pull requests: - extended support for allocate_on with ArrayPartition (#220) (@mateuszbaran)

- Julia
Published by github-actions[bot] about 1 year ago

ManifoldsBase v0.15.23

Diff since v0.15.22

Added

a field point to ValidationFibreVector to potentially store the point of the vector.
a field store_base_point to ValidationManifold to indicate whether for new fibre vectors the base point should be stored.
a keyword ignore_contexts to ValidationManifold to ignore certain contexts from validation, such as :Input, :Output, :Point, or :Vector.
a keyword ignore_functions to ValidationFibreVector to ignore certain contexts within a single function. This is provided as a dictionary with the key being the (allocating) function and the value is a context or vector of contexts.

Changed

the internal function array_value was renamed to internal_value and is now exported, since it can be also used on elements that store values different from arrays, e.g. a ValidationMPoint storing a subtype of a ManifoldPoint. array_value is hence deprecated.
Minimum Julia version is now 1.10 (the LTS which replaced 1.6)

ManifoldsBase v0.15.17

Diff since v0.15.16

Changed

Mildly breaking: the number system parameter now corresponds to the coefficients standing in front of basis vectors in a linear combination instead of components of a vector. For example, DefaultOrthonormalBasis() == DefaultOrthonormalBasis(ℝ) of DefaultManifold(3, field=ℂ) now has 6 vectors, and DefaultOrthonormalBasis(ℂ) of the same manifold has 3 basis vectors.
