Method Summary

Modifier and Type	Method and Description
T	constant(double value) Generate a constant Derivative.
default Field<T>	getField() Get the Field to which the generated derivatives belongs.
List<ParameterDriver>	getSelected() Get the parameters selected for estimation.
T	variable(ParameterDriver driver) Generate a Derivative representing the parameter driver either as a canonical variable or a constant.

Method Detail

getSelected

List<ParameterDriver> getSelected()

Get the parameters selected for estimation.

Returns:

parameters selected for estimation

constant

T constant(double value)

Generate a constant Derivative.

Parameters:

value - value of the constant

Returns:

constant Derivative

variable

T variable(ParameterDriver driver)

Generate a Derivative representing the parameter driver either as a canonical variable or a constant.

The instance created is a variable only if the parameter has been selected for estimation, otherwise it is a constant.

Parameters:

driver - driver for the variable

Returns:

variable Derivative

getField

default Field<T> getField()

Get the Field to which the generated derivatives belongs.

Returns:

Field to which the generated derivatives belongs
