package AppCont
---Purpose: This package provides the least square algorithms
-- necessary to approximate a set of continous curves
-- or a continous surface.
--
--
-- It also provides an instantiation of these algorithms
-- for a class Function, a function f(t).
-- The user will have to inherit class Function to use it.
---Level : Advanced.
-- All methods of all classes will be advanced.

is
deferred generic class TheLineTool; --- Template
---Purpose: Tool describing a continous MultiLine.
-- The MultiLine is described by a parameter.
deferred generic class TheSurfTool; --- Template
---Purpose: Tool describing a continous Surface.
-- The Surface is described by a couple of parameters.
-------------------------------
--- Algorithms:
-------------------------------
---Purpose: The two following algorithms are using the same recipe:
-- Minimizing the difference between the approximate result
-- Curve or Surface and respectively a continous MultiLine
-- or a continous surface.
generic class LeastSquare;
---Purpose: makes an approximation of a continous Line described by
-- the tool TheLineTool.
generic class SurfLeastSquare;
---Purpose: makes an approximation of a continous Surface
-- described by the tool TheSurfaceTool.
------------------------------------------------------
--- Necessary class for approximation a function f(t):
------------------------------------------------------
deferred class Function;
---Purpose: This class must be provided by the user to use the
-- approximation algorithm FittingCurve.
class FunctionTool;
---Purpose: This class is the inteface between the Function
-- class and the tool asked by LeastSquare.
---------------------------------------------------------
--- Necessary class for approximation a 2d function f(t):
---------------------------------------------------------
deferred class Function2d;
---Purpose: This class must be provided by the user to use the
-- approximation algorithm FittingCurve2d.
class FunctionTool2d;
---Purpose: This class is the inteface between the Function2d
-- class and the tool asked by LeastSquare.
class FitFunction instantiates LeastSquare from AppCont
(Function from AppCont, FunctionTool from AppCont);
class FitFunction2d instantiates LeastSquare from AppCont
(Function2d from AppCont, FunctionTool2d from AppCont);
end AppCont;
