### Problem Description
I'm trying to solve a sparse __symmetric__ system;
Originally my matrix is CSC, square, only lower triangle is stored.
This is how I create sparse hip matrix:
```c

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?

Implement LU decomposition-based linear system solver,
1. Triangular system solver
2. LU decomposition

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…

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…

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…

### 🚀 The feature, motivation and pitch
As discussed in https://github.com/pytorch/pytorch/issues/77764#issuecomment-1472510169 it would be helpful to have a CPU fallback for [`torch.addmv`](https:…

Hello!
I was wondering whether the actual definitions of Lower and Upper triangular matrices contain the leading diagonal elements. I have done some research online (http://mathworld.wolfram.com/Lowe…
