name | - identifier for method | |

order | - approximation order of method | |

s | - number of stages, this is the dimension of the matrices below | |

At | - Butcher table of stage coefficients for stiff part (dimension s*s, row-major) | |

bt | - Butcher table for completing the stiff part of the step (dimension s; NULL to use the last row of At) | |

ct | - Abscissa of each stiff stage (dimension s, NULL to use row sums of At) | |

A | - Non-stiff stage coefficients (dimension s*s, row-major) | |

b | - Non-stiff step completion table (dimension s; NULL to use last row of At) | |

c | - Non-stiff abscissa (dimension s; NULL to use row sums of A) | |

bembedt | - Stiff part of completion table for embedded method (dimension s; NULL if not available) | |

bembed | - Non-stiff part of completion table for embedded method (dimension s; NULL to use bembedt if provided) | |

pinterp | - Order of the interpolation scheme, equal to the number of columns of binterpt and binterp | |

binterpt | - Coefficients of the interpolation formula for the stiff part (dimension s*pinterp) | |

binterp | - Coefficients of the interpolation formula for the non-stiff part (dimension s*pinterp; NULL to reuse binterpt) |
