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. :-)

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).
