### Explain what you would like to see improved and how.
MATLAB and numpy offer numerical derivatives of an array, while ROOT does not. But it offers the opposite, `TH1::Integral`.
Some users do…

Hello,
First of all, thanks for maintaining this nice repo!
In the ```hopper_example.cc```, I have added this line to check derivatives.
```
solver->SetOption("derivative_test", "first-order")

I was wondering how difficult it would be to add support for CPE elements for circuit simulations. Currently, the circuit simulator doesn't seem to support it.

As the title says, when linearizing equations of motion in order to obtain control, the odd thing happens: if equilibrium point is not all zeros, the output from linearizer contains speed derivatives,…

In this issue I will try to outline a general API for all types of curves we are going to support.
Legend:
* :new: there is no such method in the base class yet, it has to be introduced to support…

Write boilerplate code for using RHS written for Boost odeint, so we can directly apply models from Epiverse-Trace `epidemics` Rcpp package - see [here](https://github.com/epiverse-trace/epidemics/tre…

right now, the `fit.Func1D` and `fit.FuncND` automatically compute the gradient of the provided function to fit, using `gonum/diff/fd` (a package that applies numerical differentiation to approximate …

Shall we add some onboarding tutorials/notebooks for new students? I'm thinking some introductions to DG / spectral methods, numerical derivatives, time steppers, etc to introduce/motivate our numeric…

I'd like to suggest moving the `pysindy` package out of the business of calculating derivatives and improve the interface to allow other packages to plug into `pysindy`.
