descriptionVarious solvers for ODEs
Ryu (DonRyuDragoni)




Build Status Published Version Documentation

Provide generic solvers for ODEs using different methods. Also, allow the user to choose which datatype they desire to use for that problem, be it f32, u8 or some non-standard bignum type..

By no means this is yet ready for any serious use right now. The code needs to be cleaned and there is a lot yet to be implemented.


use ode::{Method, Solver};

let ini_cond: Vec<f32> = vec![1., 2.];

// simple config
Solver::new(&ini_cond, |t: &f32, _: &Vec<f32>| vec![2.*t])

// complex config
let mut s = Solver::new(&ini_cond, |t: &f32, _: &Vec<f32>| vec![2.*t] );

// run the solver
let (times, pos) = s.run();

Current Goals

For the next minor version (0.2.0)

  • more and better documentation;
  • re-implement the 4th order Runge-Kutta method;
  • have at least a few tests and examples;
  • stabilize the API.

For the next major version (1.0.0)

  • figure out a generic way to write all Runge-Kutta variants that is both easy to maintain and clean to read;
  • implement all planned Runge-Kutta variants:
    • 2;
    • 3;
    • 4;
    • 5.

Release Notes

  • 0.?.? [WIP]

  • 0.1.2: break change

    Change the Number trait to use num_traits crate, so that accepted types are more consistent with what is already present in the community.

    To keep consistency with function names, solver::Solver::change_weight() is now called solver::Solver::weights().

    Also, a bit more of documentation.

    RK4 is back online, and the only usable method so far.

  • 0.1.1 [unusable]: break change

    Closing issue #1, this drops the MATLAB-ish style in favor of a more Rustic way of doing things. This also starts the process of building version 0.2.0, attempting to stabilize the API.

    This is not a usable version, as solver::Solver::run() will always return empty vectors.

  • 0.1.0: first draft

    Started the project as an attempt to bring MATLAB-ish ODE solvers to Rust. The API is completelly unstable and may change at any time.

    Only the RK4 method is available, with a very basic usage.
