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. |

29 | ---Level : Advanced. |
30 | -- All methods of all classes will be advanced. |

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. |
