17 | package AppCont | |

18 | ||

19 | ---Purpose: This package provides the least square algorithms | |

20 | -- necessary to approximate a set of continous curves | |

21 | -- or a continous surface. | |

22 | -- | |

23 | -- | |

24 | -- It also provides an instantiation of these algorithms | |

25 | -- for a class Function, a function f(t). | |

26 | -- The user will have to inherit class Function to use it. | |

27 | ||

28 | ||

29 | ---Level : Advanced. | |

30 | -- All methods of all classes will be advanced. | |

42 | deferred generic class TheLineTool; --- Template | |

43 | ---Purpose: Tool describing a continous MultiLine. | |

44 | -- The MultiLine is described by a parameter. | |

56 | ---Purpose: The two following algorithms are using the same recipe: | |

57 | -- Minimizing the difference between the approximate result | |

58 | -- Curve or Surface and respectively a continous MultiLine | |

59 | -- or a continous surface. | |

60 | ||

61 | generic class LeastSquare; | |

62 | ---Purpose: makes an approximation of a continous Line described by | |

63 | -- the tool TheLineTool. | |

64 | ||

65 | generic class SurfLeastSquare; | |

66 | ---Purpose: makes an approximation of a continous Surface | |

67 | -- described by the tool TheSurfaceTool. | |
