projection onto tangent space to unitary matrices

8

I don't think that the current implementation of `project(::OrthogonalMatrices, p, X)` works as intended. For any X in the tangent space, the projection should act as the identity operator, but...

Docs, Lie group actions are non-commutative (i.e. non-symmetric)

2

Hi, I just want to confirm one line in the docs for `exp_lie`. I have Lie group actions in general as non-commutative? https://github.com/JuliaManifolds/Manifolds.jl/blob/8274392cc6a1c406f7fe83012e2feefb85e58738/src/groups/group.jl#L846 My concern is that the composition operation...

Speedup CI :magic_wand:

16

This is an idea to speed up CI, I did a small benchmark, see #144 and it seems from https://github.com/JuliaDiff/ChainRules.jl/pull/499/files#diff-3b9314a6f9f2d7eec1d0ef69fa76cfabafdbe6d0df923768f9ec32f27a249c63R27-R32 one can set the compiler flags, though I am not...

Speed up CI

21

There are a few more things we can do to speed up CI and avoid timeouts: 1. Split the tests into groups that are run in parallel. Choose an environment...

Make the current ODE-based exp solver only work in charts

18

That's a quick sketch of the change discussed in https://github.com/JuliaManifolds/Manifolds.jl/pull/429 . This ODE-based implementation of `exp` only works on R^n with a metric (or a connection) so this makes it...

Good day, Please see a new tutorial for `SpecialEuclidean(2)`. There are things I still want to add, but this should be a good baseline point to clean up as needed...
