Go package with ordinary differential equations solvers for initial value problems to be solved by explicit methods.
The package features methods for float32
float64
complex64
and complex128
types.
The methods implemented so far are,
- Euler
- Mid point
- Runge-Kutta 4
The package is easily extensible to provide other methods.
The API is pretty consistent, and you'll get it easily,
Type specific docs,
- GoDoc documentation for float32
- GoDoc documentation for float64
- GoDoc documentation for complex64
- GoDoc documentation for complex128
Import the type you intend to use. For the recommended float64
just type
import "github.com/Daniel-M/odeint/float64"
and you are ready to use methods. The stepper used (euler, mid point or Runge-Kutta-4) can be changed easily.
To get a feeling of the usage check the files under examples/brusselator
. You will see that to change the method used
you just need to change the integrator used (line 38 of examples/brusselator/rk4
source code).
You might be thinking, why does this guy have a subpackage for each numeric type? Well, though it makes the package harder to maintain, having type specific integrators is a priority for me. I could have used interface-based integrators but it would be at the expense of the extensibility of the integrators to more custom numerical types, a feature which I find relevant too.
You can run all tests with
go test -v ./...
or individual type oriented tests as
go test -v ./float64 # For float64 type
- Support higher order methods.
- Implement adaptative step methods.
