Error when mixing datatypes while differentiating using ForwardDiff and using FunctionWrapperSpecialize

This MWE ```julia using DifferentialEquations using ForwardDiff: gradient function ode_f(du, u, p, t) x = u[1] v = u[2] dx = v dv = -x du[1] = dx du[2] =...

matrix SDE problem with non-diagonal noise

1

Hi, I'm trying to solve the matrix SDE problem $dA = AD_1 dW_1+D_2AdW_2$, where $A$, $D_1$ and $D_2$ are $n\times n$ matrices. I'm wondering what noise prototype I should use?...

Separate all automatic algorithm selection functionalities from their packages

We can either move them all to one package or create separate packages for each of them. This will help reduce loading times and dependencies in the packages that have...

Ensemble plot, single component

3

It's conceivable that I'm just confused, but I've been trying to plot a single component of an EnsembleSummary for 18 dimensional SDE following the documentation here: https://docs.sciml.ai/DiffEqDocs/stable/features/ensemble/#Example-4:-Using-the-Analysis-Tools where it says:...

Wrong integrator.t (t not in tstops) send to callback during Zygote gradient calculation.

Not entirely sure if this should fall under DifferentialEquations.jl but here we go. I am implementing a NeuralODE using callbacks myself using DifferentialEquations (not using DiffEqFlux atm). I am noticing...

I am trying to compute some loss function of an ODE problem, and while checking the type-stability of my algorithm, I found out that using auto-switching ode solvers broke the...

Hi, I’m trying to use callbacks to create pulses to two identical systems ran through the same set of differential equations. It seems like putting the two Callbacks together results...

Manual changes to precompile options in `LocalPreferences.jl` not recognized

1

First of all, thanks for adding the ability to selectively [enable/disable precompilation](https://docs.sciml.ai/DiffEqDocs/stable/features/low_dep/#Controlling-Function-Specialization-and-Precompilation), this makes it much nicer on the user for certain work loads 👍 However, one thing I've noticed...
