Package __Manifolds.jl__ aims to provide both a unified interface to define and
use manifolds as well as a library of manifolds to use for your projects.
This package is mostly stable, see https://github.com/JuliaManifolds/Manifolds.jl/issues/438 for planned upcoming changes.
## Getting started
To install the package just type
```julia
using Pkg; Pkg.add("Manifolds")
```
Then you can directly start, for example to stop half way from the north pole on the [`Sphere`](https://juliamanifolds.github.io/Manifolds.jl/stable/manifolds/sphere.html) to a point on the equator, you can generate the [`shortest_geodesic`](https://juliamanifolds.github.io/ManifoldsBase.jl/stable/functions.html#ManifoldsBase.shortest_geodesic-Tuple{AbstractManifold,%20Any,%20Any}).
It internally employs [`exp`](https://juliamanifolds.github.io/ManifoldsBase.jl/stable/functions.html#Base.exp-Tuple{AbstractManifold,%20Any,%20Any}) and [`log`](https://juliamanifolds.github.io/ManifoldsBase.jl/stable/functions.html#Base.log-Tuple{AbstractManifold,%20Any,%20Any}).
```julia
using Manifolds
M = Sphere(2)
γ = shortest_geodesic(M, [0., 0., 1.], [0., 1., 0.])
γ(0.5)
```
## Ecosystem highlights
* A wide selection of Riemannian manifolds like spheres, hyperbolic spaces, Stiefel and Grassmann manifolds.
* Support for optimization on manifolds using [Manopt.jl](https://github.com/JuliaManifolds/Manopt.jl/).
* Support for many operations used in optimization and manifold-valued statistics with a focus on performance and ease of use.
* Connection manifolds.
* Lie groups.
* Atlases, charts and custom metrics (work in progress).
* A lightweight interface package: [ManifoldsBase.jl](https://github.com/JuliaManifolds/ManifoldsBase.jl).
* Differential equations on manifolds: [ManifoldDiffEq.jl](https://github.com/JuliaManifolds/ManifoldDiffEq.jl).
* Finite differences and automatic differentiation on manifolds using [ManifoldDiff.jl](https://github.com/JuliaManifolds/ManifoldDiff.jl) (work in progress).
* Integration and measures on manifolds: [ManifoldMeasures.jl](https://github.com/JuliaManifolds/ManifoldMeasures.jl) (work in progress).
* Functional manifolds: [FunManifolds.jl](https://github.com/JuliaManifolds/FunManifolds.jl) (work in progress).
## Support
If you have any questions regarding the Manifolds.jl ecosystem feel free to reach us using [Github discussion forums](https://github.com/JuliaManifolds/Manifolds.jl/discussions), [Julia Slack](https://julialang.org/slack/), [Julia Zulip](https://julialang.zulipchat.com/) or [Julia discourse](https://discourse.julialang.org/) forums. We are interested in new applications and methods on manifolds -- sharing your work is welcome!
