\subsection{Detailed Description}
Implementation of the S\+VD complete incremental policy to act as a wrapper when accessing S\+VD complete decomposition from within \doxyref{C\+F\+Type}{p.}{classmlpack_1_1cf_1_1CFType}. 

An example of how to use \doxyref{S\+V\+D\+Complete\+Policy}{p.}{classmlpack_1_1cf_1_1SVDCompletePolicy} in CF is shown below\+:


\begin{DoxyCode}
\textcolor{keyword}{extern} arma::mat data; \textcolor{comment}{// data is a (user, item, rating) table.}
\textcolor{comment}{// Users for whom recommendations are generated.}
\textcolor{keyword}{extern} arma::Col<size\_t> users;
arma::Mat<size\_t> recommendations; \textcolor{comment}{// Resulting recommendations.}

CFType<SVDCompletePolicy> cf(data);

\textcolor{comment}{// Generate 10 recommendations for all users.}
cf.GetRecommendations(10, recommendations);
\end{DoxyCode}
