          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 correction step, so implementations of this interface may return a modified measurement noise depending on the current iteration step.

Returns:
the measurement noise matrix
