17 private class FunctionH from Bisector
19 inherits FunctionWithDerivative from math
22 ---Purpose: H(v) = (T1 .P2(v) - P1) * ||T(v)|| -
24 -- (T(v).P2(v) - P1) * ||T1||
33 Create (C2 : Curve from Geom2d ;
36 returns FunctionH from Bisector;
38 Value(me : in out; X : Real; F : out Real)
39 ---Purpose: Computes the values of the Functions for the variable <X>.
42 Derivative(me : in out; X : Real; D : out Real)
45 Values(me : in out ; X : Real; F : out Real; D : out Real)
46 ---Purpose: Returns the values of the functions and the derivatives
47 -- for the variable <X>.
