deferred class FunctionSetWithDerivatives from math
inherits FunctionSet
---Purpose: This abstract class describes the virtual functions associated
-- with a set of N Functions each of M independant variables.
uses Vector from math, Matrix from math
is
NbVariables(me)
---Purpose: Returns the number of variables of the function.
returns Integer
is deferred;
NbEquations(me)
---Purpose: Returns the number of equations of the function.
returns Integer
is deferred;
Value(me: in out; X: Vector; F: out Vector)
---Purpose: Computes the values <F> of the Functions for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean
is deferred;
Derivatives(me: in out; X: Vector; D: out Matrix)
---Purpose: Returns the values <D> of the derivatives for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean
is deferred;
Values(me: in out; X: Vector; F: out Vector; D: out Matrix)
---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
