@author Vincent Garcia @author Frank Nielsen @version 1.0 @section LicenseSee file LICENSE.txt @section DescriptionThe multivariate Gaussian distribution is an exponential family and, as a consequence, the probability density function is given by \f[ f(x; \mathbf{\Theta}) = \exp \left( \langle t(x), \mathbf{\Theta} \rangle - F(\mathbf{\Theta}) + k(x) \right) \f] where \f$ \mathbf{\Theta} \f$ are the natural parameters. This class implements the different functions allowing to express a multivariate Gaussian distribution as a member of an exponential family. @section ParametersThe parameters of a given distribution are: - Source parameters \f$\mathbf{\Lambda} = ( \mu , \Sigma ) \mbox{ with } \mu \in \mathds{R}^d \mbox{ and } \Sigma \succ 0\f$ - Natural parameters \f$\mathbf{\Theta} = ( \theta , \Theta )\f$ - Expectation parameters \f$\mathbf{H} = ( \eta , H )\f$
