 function [co] = IRenyi_HRenyi_initialization(mult)
%Initialization of the "meta" Renyi mutual information estimator. The estimator uses the identity:
%I_{alpha}(X) = H_{alpha}(Z), where Z =[F_1(X_1);...;F_d(X_d)] is the copula transformation of X; F_i is the cdf of X_i.
%
%Note:
% 1)The estimator is treated as a cost object (co).
% 2)We make use of the naming convention 'I<name>_estimation', to ease embedding new mutual information estimation methods.
%
%INPUT:
% mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
