Description |
Solution of ordinary differential equation (ODE) initial value problems.
http://www.gnu.org/software/gsl/manual/html_node/Ordinary-Differential-Equations.html
A simple example:
import Numeric.GSL
import Numeric.LinearAlgebra
import Graphics.Plot
xdot t [x,v] = [v, -0.95*x - 0.1*v]
ts = linspace 100 (0,20)
sol = odeSolve xdot [10,0] ts
main = mplot (ts : toColumns sol) |

Stepping functions
| Constructors | RK2 | Embedded Runge-Kutta (2, 3) method.
| RK4 | 4th order (classical) Runge-Kutta. The error estimate is obtained by halving the step-size. For more efficient estimate of the error, use RKf45.
| RKf45 | Embedded Runge-Kutta-Fehlberg (4, 5) method. This method is a good general-purpose integrator.
| RKck | Embedded Runge-Kutta Cash-Karp (4, 5) method.
| RK8pd | Embedded Runge-Kutta Prince-Dormand (8,9) method.
| RK2imp | Implicit 2nd order Runge-Kutta at Gaussian points.
| RK4imp | Implicit 4th order Runge-Kutta at Gaussian points.
| BSimp | Implicit Bulirsch-Stoer method of Bader and Deuflhard. This algorithm requires the Jacobian.
| Gear1 | M=1 implicit Gear method.
| Gear2 | M=2 implicit Gear method.
