23 deferred class FunctionSet from math
25 -- This abstract class describes the virtual functions associated to
26 -- a set on N Functions of M independant variables.
32 Delete(me:out) is virtual;
33 ---C++: alias "Standard_EXPORT virtual ~math_FunctionSet(){Delete();}"
36 ---Purpose: Returns the number of variables of the function.
43 ---Purpose: Returns the number of equations of the function.
49 Value(me: in out; X: Vector; F: out Vector)
50 ---Purpose: Computes the values <F> of the functions for the
52 -- returns True if the computation was done successfully,
59 GetStateNumber(me: in out)
60 ---Purpose: Returns the state of the function corresponding to the
61 -- latestcall of any methods associated with the function.
62 -- This function is called by each of the algorithms
63 -- described later which define the function Integer
64 -- Algorithm::StateNumber(). The algorithm has the
65 -- responsibility to call this function when it has found
66 -- a solution (i.e. a root or a minimum) and has to maintain
67 -- the association between the solution found and this
69 -- Byu default, this method returns 0 (which means for the
70 -- algorithm: no state has been saved). It is the
71 -- responsibility of the programmer to decide if he needs
72 -- to save the current state of the function and to return
73 -- an Integer that allows retrieval of the state.
