Interface MeasurementModel

All Known Implementing Classes:

DefaultMeasurementModel

public interface MeasurementModel

Defines the measurement model for the use with a KalmanFilter.

Version:

$Id$

Method Summary

RealMatrix	getMeasurementMatrix() Returns the measurement matrix.
RealMatrix	getMeasurementNoise() Returns the measurement noise matrix.

Method Detail

getMeasurementMatrix

RealMatrix getMeasurementMatrix()

Returns the measurement matrix.

Returns:

the measurement matrix

getMeasurementNoise

RealMatrix getMeasurementNoise()

Returns the measurement noise matrix. This method is called by the KalmanFilter every correct step, so implementations of this interface may return a modified measurement noise depending on current iteration step.

Returns:

the measurement noise matrix
