freude

The freude crate will provide steppers and integrators to solve ODEs (ordinary differential equations). It is inspired by boost::numeric::odeint. At the moment it only supports the explicit, fixed-step Euler, Heun, and 4-th order Runge Kutta (RK4) methods.

Todo

Pretty much everything. :-)

Recent changes

• 0.3
  • Update to ndarray 0.9
  • Unify Vec and ArrayBase stepper states through ndarray's Zip and IntoNdProducer traits
  • Provide several examples as benchmarks (Kuramoto and Chaotic Neural Network models)

Trivia

The crate's name freude is inspired by Beethoven's Ode an die Freude (“Ode to Joy”), and can be pronounced either /ˈfʀɔɪ̯də/ or, alternatively, froy-D-E (as in O-D-E).
