16  * (inv_range,yaw) variable.
17  * The parameter space of this ellipsoid comprises these variables (in this
18  * order):
19  * - inv_range: The inverse distance from the sensor to the feature.
20  * - yaw: Angle for the rotation around +Z ("azimuth").
21  *
22  * This parameterization is a 2D version of that presented in the paper:
23  * - Civera, J. and Davison, A.J. and Montiel, J., "Inverse depth
24  * parametrization for monocular SLAM", T-RO, 2008.
25  *
26  * This class expects you to provide a mean vector of length 4 and a 4x4
27  * covariance matrix, set with \a setCovMatrixAndMean().
28  *
30  * CGeneralizedEllipsoidTemplate::setQuantiles() for learning
31  * the mathematical details about setting the desired confidence interval.
