/**
* Robustly estimates magnetometer hard-iron biases, cross couplings and
* scaling factors using PROMedS algorithm.
* <p>
* To use this calibrator at least 10 measurements taken at a single known
* position and instant must be taken at 10 different unknown orientations and
* zero velocity when common z-axis is assumed, otherwise at least 13
* measurements are required.
* <p>
* Measured magnetic flux density is assumed to follow the model shown below:
* <pre>
* mBmeas = bm + (I + Mm) * mBtrue + w
* </pre>
* 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.
