When combining 100s of simulated PEMD lenses, the H0 recovery precision (0.4%) approaches a point where the numerical precision level of the lens equation solver starts to matter. My solution for forc…

As stated in the [Nutils Book](https://nutils.org/install-performance.html), _Nutils is not (yet) the fastest tool in its class_. I experience that in our [perpendicular-flap](https://github.com/preci…

I wanted a time-reversible integrator, and according to the documentation SemiImplicitEuler() should work.
However, I ran the following:
```python
def f(t, p, args):
return -p
def g(t, q, a…

Hi Rok, I've had some more time to play with the code and one thing that crops up is that `G` will sometimes get rejected for not being positive definite, even though it is. I believe it's just a nume…

In the process of replicating the graphics, the beam mode from the results of the joint beamforming optimization was well shifted, and the communication beam at 90° and 135° I simulated was wrong. Why…

As Arin, a person who wants to calculate the derivative of trigonometric and logarithimic functions, I want an algorithim that can interpret, evaluate, and differentiate these types of functions.

This is not technically a real matrix operation, but it is commonly needed, particularly for scaling. Right now, the approach commonly used is:
```js
const inverse = ops.getMultiplicativeInverse(…

Currently the documentation is missing any real description of the methods employed, both in terms of the underlying mathematics and the numerical solver implementations. Whilst references to papers a…
