private class PrjFunc from ProjLib inherits FunctionSetWithDerivatives from math
---Purpose:
uses
Vector from math,
Matrix from math,
CurvePtr from Adaptor3d,
SurfacePtr from Adaptor3d,
Pnt2d from gp
raises ConstructionError
is
Create (C: CurvePtr from Adaptor3d; FixVal: Real from Standard; S: SurfacePtr from Adaptor3d; Fix: Integer)
returns PrjFunc
raises ConstructionError;
NbVariables(me)
---Purpose: returns the number of variables of the function.
returns Integer;
NbEquations(me)
---Purpose: returns the number of equations of the function.
returns Integer;
Value(me: in out; X: Vector from math; F: out Vector from math)
---Purpose: computes the values <F> of the Functions for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean;
Derivatives(me: in out; X: Vector from math; D: out Matrix from math)
---Purpose: returns the values <D> of the derivatives for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean;
Values(me: in out; X: Vector from math; F: out Vector from math; D: out Matrix from math)
---Purpose: returns the values <F> of the functions and the derivatives
-- <D> for the variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean;
Solution(me) returns Pnt2d from gp;
---Purpose: returns point on surface
fields
