We fix several related issues in hyperbolic geometry:
- `moebius_transform` wrong in the orientation-reversing
(negative determinant) case
- `midpoint` and `perpendicular_bisector`
gave differe…

The following computation takes a lot of time:

Hi,
I was wondering whether a couple of algorithms that are about learning metrics and embeddings would be within the scope.
Specifically, if the following two algorithms (either individually …

I think this should be its separate submodule so that each object can be in its own file: `nyx::bodies::Earth;` . This will be quite verbose for sure, but it'll allow for clarity.
Just like in `pro…

When dealing with transforms that only contain position, orientation and possibly scale many operations can be performed more efficiently than using a general purpose matrix.
A while ago I experime…

### Describe your issue.
As first discussed in #10974 , I obtained wrong results when trying to approximate the SVD of a matrix with LOBPCG. ARPACK is fine.
The matrix can be found as a txt file a…

Moving forward, we will need some kind of math library for Graphite.
Graphite is a 2D raster and vector graphics editor.
We have gathered a few criteria that seemed important to us:
