26 | ---Purpose: This package provides algorithms approximating a function |
27 | -- that can be multidimensional creating in the end a |
28 | -- BSpline function with the required continuity |

63 | ---Purpose : |
64 | -- this class is used to choose the way of cutting if needed |
65 | |
66 | class DichoCutting; |
67 | ---Purpose : |
68 | -- inherits class Cutting; |
69 | -- if Cutting is necessary in [a,b], we cut at (a+b) / 2. |
70 | -- |
71 | |
72 | class PrefCutting; |
73 | ---Purpose : |
74 | -- inherits class Cutting; contains a list of preferential points (di)i |
75 | -- if Cutting is necessary in [a,b], we cut at the di nearest from (a+b)/2. |
76 | |
77 | class PrefAndRec; |
78 | ---Purpose : |
79 | -- inherits class Cutting; contains two lists of preferential points to |
80 | -- manage to level of preferential cutting. |
81 | -- if Cutting is necessary in [a,b], we cut at the di nearest from (a+b)/2 |
