17 deferred class MultipleVarFunction from math
19 -- Describes the virtual functions associated with a multiple variable function.
23 Delete(me:out) is virtual;
24 ---C++: alias "Standard_EXPORT virtual ~math_MultipleVarFunction(){Delete();}"
28 -- Returns the number of variables of the function
34 Value(me: in out; X: Vector; F: out Real)
35 ---Purpose: Computes the values of the Functions <F> for the
37 -- returns True if the computation was done successfully,
44 GetStateNumber(me: in out)
45 ---Purpose: return the state of the function corresponding to the latestt
46 -- call of any methods associated to the function. This
47 -- function is called by each of the algorithms described
48 -- later which define the function Integer
49 -- Algorithm::StateNumber(). The algorithm has the
50 -- responsibility to call this function when it has found
51 -- a solution (i.e. a root or a minimum) and has to maintain
52 -- the association between the solution found and this
54 -- Byu default, this method returns 0 (which means for the
55 -- algorithm: no state has been saved). It is the
56 -- responsibility of the programmer to decide if he needs
57 -- to save the current state of the function and to return
58 -- an Integer that allows retrieval of the state.
