Thanks for creating such a nice library.
I have experienced numerical instability in the Multivariate Gaussian Distributions. For better numerical stability, I wondered if it would be better replac…

linear algebra functions should uniformly accept empty (size=0) arrays. Most of them should return empty output on empty input. The key thing to make sure is that the dtype of the (empty) output is co…

The README file says we'll be tested on whether solve_upper_triangular returns the correct result when U is a LOWER triangular matrix. Is that accurate? If so, what is it supposed to do in that case?

For very specific uses of solve_triangular, the parallelization performance seems to degrade after 1.4.1. Here is an short example:
```
# Imports

In the case of `solve_upper_triangular`, for N of greater than about 70 in the upper triangular matrix my tests will pass only about 50% of the time, with the other times the error being far greater t…

I am trying to solve a sparse linear system with Vectorz, but it seems to lack some basic algorithms to do it efficiently.
I want to solve Ku=F, where K is a sparse matrix and F a dense vector.
The c…

Hi, is this package still maintained? I don't see any recent commits. Tests are failing on latest scipy with
```
cv_sol = solve_triangular(cv_chol, (X - mu).T, lower=True).T

Hi!
My thanks for making this toolbox available. Extremely useful!
I was testing it out using a simple squared exponential kernel to build the matrices, but run into an unexpected error (sometim…
