Declares a class that represents a Probability Density function (PDF) of a 3D pose using a quaternion .
This class implements that PDF using a mono-modal Gaussian distribution. See mrpt::poses::CPose3DQuatPDF for more details, or mrpt::poses::CPose3DPDF for classes based on Euler angles instead.
Uncertainty of pose composition operations ( ) is implemented in the methods "CPose3DQuatPDFGaussian::operator+=" and "CPose3DQuatPDF::jacobiansPoseComposition".
For further details on implemented methods and the theory behind them, see this report.
