Detailed Description

This class describes an elementary covariance.

This covariance is described through the following list of parameters:

the covariance type: the list of these types is provided in ECov.hpp
the largest set of parameters for any covariance: range(s), anisotropy angle(s), third parameter. Some of these parameters do not make sense, depending on the covariance type: e.g. the range for nugget effect, the third parameter for a spherical structure, ... All these parameters are processed and stored as a tensor in order to avoid repetitive calculations.
the sill. This comes as a square symmetric matrix whose dimension is equal to the number of variables.
