You may want to have a look at the repo https://github.com/stegu/psrdnoise/ for a set of modern improved noise functions by me and Ian McEwan. These are both better and faster than the functions we pu…

There is some NaN's and discrepancies for theta=0 case. Either Ffermi_derivatives_m_n_quad or reference values from Mma are wrong. Or both...

Refprop does not return correct derivatives in the two-phase region. There are ways to calculate the correct values from saturation properties, especially for density. An if-clause should be used to d…

Hi,
Is there an alternative way to describe the PDE to solve that doesn't require the use of ModelingToolkit or Symbolics? For example, if I were to need to write:
```julia
Differential(x)(g(x)*…

Hi,
applying jax.grad to a function which uses diffrax to integrate a piecewise defined ODE, I observe that one partial derivative is unexpectedly zero. The ODE solver returns correct function values…

The following code yields the identity, as it should
```
function f1(dx, x)
for i in 1:length(x)
dx[i] = x[i]^2

There's two components to this enhancement.
### Optimization
Define a `theta` and `eta` (inverse `theta`) function to transform parameters between an open bounded interval to a closed bounded inte…
