Method Detail

getSelected

List<org.orekit.utils.ParameterDriver> getSelected()

Get the parameters selected for estimation.

Returns:

parameters selected for estimation

constant

org.hipparchus.analysis.differentiation.DerivativeStructure constant(double value)

Generate a constant DerivativeStructure.

Parameters:

value - value of the constant

Returns:

constant DerivativeStructure

variable

org.hipparchus.analysis.differentiation.DerivativeStructure variable(org.orekit.utils.ParameterDriver driver)

Generate a DerivativeStructure 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 DerivativeStructure
