GClasses::GDataRowSplitter Class Reference

Detailed Description

This class divides a features and labels matrix into two parts by randomly assigning each row to one of the two parts, keeping the corresponding rows together. The rows are shallow-copied. The destructor of this class releases all of the row references.
