deferred class MultipleVarFunction from math
|
|
---Purpose:
|
|
-- Describes the virtual functions associated with a multiple variable function.
|
|
uses Vector from math

is
|
|

|
NbVariables(me)
|
|
---Purpose:
|
|
-- Returns the number of variables of the function
|
|
|
|
returns Integer
|
|
is deferred;
|
|
|
|
|
|
Value(me: in out; X: Vector; F: out Real)
|
|
---Purpose: Computes the values of the Functions <F> for the
|
|
-- variable <X>.
|
|
-- returns True if the computation was done successfully,
|
|
-- otherwise false.
|
|
|
|
returns Boolean
|
|
is deferred;
|
|
|
|
|
|
GetStateNumber(me: in out)
|
|
---Purpose: return the state of the function corresponding to the latestt
|
|
-- call of any methods associated to the function. This
|
|
-- function is called by each of the algorithms described
|
|
-- later which define the function Integer
|
|
-- Algorithm::StateNumber(). The algorithm has the
|
|
-- responsibility to call this function when it has found
|
|
-- a solution (i.e. a root or a minimum) and has to maintain
|
|
-- the association between the solution found and this
|
|
-- StateNumber.
|
|
-- Byu default, this method returns 0 (which means for the
|
|
-- algorithm: no state has been saved). It is the
|
|
-- responsibility of the programmer to decide if he needs
|
|
-- to save the current state of the function and to return
|
|
-- an Integer that allows retrieval of the state.
