public class PROSACRobustKnownHardIronMagneticFluxDensityNormMagnetometerCalibrator extends RobustKnownHardIronMagneticFluxDensityNormMagnetometerCalibrator
Robustly estimates magnetometer cross couplings and scaling factors using PROSAC algorithm.

To use this calibrator at least 7 measurements with known magnetic field norm at an unknown position and instant must be taken at 7 different unknown orientations when common z-axis is assumed, otherwise at least 10 measurements are required.

Measured magnetic flux density is assumed to follow the model shown below: 

     mBmeas = bm + (I + Mm) * mBtrue + w
Where: - mBmeas is the measured magnetic flux density. This is a 3x1 vector. - bm is magnetometer hard-iron bias. Ideally, on a perfect magnetometer, this should be a 3x1 zero vector. - I is the 3x3 identity matrix. - Mm is the 3x3 soft-iron matrix containing cross-couplings and scaling factors. Ideally, on a perfect magnetometer, this should be a 3x3 zero matrix. - mBtrue is ground-truth magnetic flux density. This is a 3x1 vector. - w is measurement noise. This is a 3x1 vector. Notice that this calibrator assumes that all measurements are taken in a short span of time, where Earth magnetic field can be assumed to be constant at provided location and instant.
