private class SearchSing from ChFi3d inherits FunctionWithDerivative from math
---Purpose: F(t) = (C1(t) - C2(t)).(C1'(t) - C2'(t));
uses Curve from Geom
is
Create(C1, C2 : Curve from Geom)
returns SearchSing from ChFi3d;
Value(me: in out; X: Real; F: out Real)
---Purpose: computes the value of the function <F> for the
-- variable <X>.
-- returns True if the computation was done successfully,
-- False otherwise.
returns Boolean;
Derivative(me: in out; X: Real; D: out Real)
---Purpose: computes the derivative <D> of the function
-- for the variable <X>.
-- Returns True if the calculation were successfully done,
-- False otherwise.
returns Boolean;
Values(me: in out; X: Real; F, D: out Real)
---Purpose: computes the value <F> and the derivative <D> of the
-- function for the variable <X>.
-- Returns True if the calculation were successfully done,
