Description Usage Arguments Details Value Author(s) References Examples

A rather simple multibody system, describing the behavior of a car axis on a bumpy road.

It is a differential algebraic equation of index 3

1 2 3 |

`yini ` |
the initial (state) values for the DE system. If |

`dyini ` |
the initial derivatives of the state variables of the DE system. |

`times ` |
time sequence for which output is wanted; the first
value of |

`method ` |
the solver to use; only |

`atol ` |
absolute error tolerance, either a scalar or a vector, one value for each y. |

`rtol ` |
relative error tolerance, either a scalar or a vector, one value for each y, |

`printmescd ` |
if TRUE the mixed error significant digits computed using the reference solution at time 3 are printed |

`parms ` |
list of parameters that overrule the default parameter values |

`... ` |
additional arguments passed to the solver . |

The default parameters are: eps = 1e-2, M = 10, L = 1, L0 = 0.5, r = 0.1, w = 10, g = 1

A matrix of class `deSolve`

with up to as many rows as elements in
`times`

and as many
columns as elements in `yini`

, plus an additional column (the first)
for the time value.

There will be one row for each element in `times`

unless the
solver returns with an unrecoverable error. If
`yini`

has a names attribute, it will be used to label the columns
of the output value.
