Solves numerically an initial conditions problem for a set of Ordinary Differential Equations (ODE) by Runge-Kutta 4 method. Integrates numerically the equations from **tmin** to **tmax** by steps of **dt**.

1 | ```
multirunge(y0, tmin, tmax, dt, param, sys)
``` |

`y0` |
Numerical vector : initial conditions (as many elements as equations in sys) |

`tmin` |
Minimum value of the independent variable (generally the time) |

`tmax` |
Maximum value of the independent variable |

`dt` |
Time increment (default = 0.01) |

`param` |
Numerical vector providing the parameters for sys |

`sys` |
The set of functions giving the right sides of the ODEs |

`sys`

must be provided by the user. Please edit the object `sys`

(see `?sys`

and examples)

A numerical vector of **nfunct** elements. Nfunct is the number of unknown functions of `sys`

determined by the function as `length(sys())`

Should seldom be used independently. Most often it will be called by **evrunge**
