\subsection{Detailed Description}
Class representing off-line data stored in memory. 

The data are stored in an internal matrix {\tt Data} . Each column of Data corresponds to one discrete time observation $t$. Access to this matrix is via indexes {\tt rowid} and {\tt delays}.

The data can be loaded from a file.

Method that assigns random variables to the datasource. Typically, the datasource will be constructed without knowledge of random variables. This method will associate existing variables with RVs. 

(Inherited from m3k, may be deprecated soon). 

Reimplemented from {\bf DS} \doxyref{}{p.}{classDS_9a35ca9c9321dce2bf63bf668f785b75}.
