Hi all,
I am trying to do visual odometry of an aircraft with a downward-looking camera with ~42° FOV. Just for a quick summary, I am optimizing an SE3 pose using the 'sba' vertices and edges. All …

```julia
A = [1.0 1.0; 1.0 1.0]
det(A) * inv(A)
# ERROR: SingularException(2)
```
to be fair, the LU approach is remarkably resiliant...
```julia
A = [1.0 1.0; 1.0 1.0-1e-16]

We have talked about implementing new `Type`s for vectors and matrices that would ideally implement interfaces of a matrix library for more advanced computations (see also https://github.com/fiji/fiji…

I would like to add the Jacobian matrix to this package. Do you have an opinion on how to implement it? It's the partial derivative of a function evaluated at a variety of X values, with respect to ea…

### Describe your issue.
I'm working on adding an `axis` argument to `scipy.stats.pearsonr`. It uses `scipy.linalg.norm` instead of (e.g.) `np.linalg.norm` because `scipy.linalg.norm` tends to avoi…

Hi,
Thank you for this great package!
Any scope to include semi nonnegative matrix factorization? Your docs seems to suggest ability to allow negative numbers in matrix to be factorized, but the…
