newton_rootfinder

newton_rootfinder is a scientific computing rust crate to solve nonlinear equation systems thanks to rootfinding methods.

Focus of the crate

This crate implements Newton's method and other derived methods.

To see a visualization of this method, you can watch this video: Newton's fractal

This crate provides methods applicable for n-dimensional problems.

It provides several parametrization options and a simulation log to monitor the resolution process.

Out of scope

This crate does NOT provide a solver for nonlinear differential equations.

This crate does NOT provide a specific solver for one dimensional problems.

Comparison with other rust crates

For the comparison with other crates that implements several fonctionalities, the module of those crate has been explicited.

Note: Crates may have evolved since this comparison was established.

If you feel that this comparison needs an update, don't hesite to open an issue or to do a pull request !

N-dimensional solver

The following crates are providing solvers based on Newton's method for n-dimensional systems.

newton_rootfinder aims to be the reference crate for n-dimensional rootfinding algorithms and is focused only on that topic.

bacon_sci::roots (0.13.1) also implements n-dimensional methods, but only for polynomials.

1-dimensional solver

If you are looking crates for one dimensional solver, newton_rootfinder is not the right one for you, but the rust ecosystem has several options :
