Hello, I have some calculations with duration matrix in my project. I am analyzing durations between "depot" and other 2 locations.I found something wrong between two results. Here is my requests with…

This is pretty confusing. The characteristic function of multivariate normal distribution `cf(d::MvNormal, t::AbstractVector)` is the simplest thing there is for it, and it seems it is not implemented…

### **Question 1:**
The first partial derivative of the log of normal distribution `(l=-log(N~(μ,σ^2)))` with respect to the parameters μ and σ is
- ∂l/∂μ = (μ - x)/σ^2
- ∂l/∂σ = (σ^2 - (μ - x)^2)…

I want to make calculations with plain molecules, but it can't be done easily with Descartes coordinates. It would be better if I could generate z-matrix input with iqmol.

We've been trying to reproduce VASP's internal calculations of optical transition matrix elements - that's not what we really want, but just to convince ourselves that we have the right wavefunctions.…

Hi all,
We should decide the future of the use of a type system in ARTS. There's numerous ideas of how to improve it in a few PRs so I thought we gather those here.
I will present only the prob…

Existing data structures in FCL do not seem to support boundary representations of polytopic solids (i.e., polyhedra in 3D). Are there any plans to incorporate such a representation? If not, how recep…

Error when selecting specific columns of the PTDF matrix I would expect that the following commands work:
```

After generating the perspective projection matrix with the glm::perspective function, we have to switch some matrix values aferwards for it to work as expected. As can be verified in [the original fi…
