Classes
class	SparseVector< Real >
class	SparseMatrix< Real >
class	GeneralMatrix
	This class is a wrapper that enables you to store a matrix in one of three forms: either as a Matrix<BaseFloat>, or a CompressedMatrix, or a SparseMatrix<BaseFloat>. More...

void	ExtractRowRangeWithPadding (const GeneralMatrix &in, int32 row_offset, int32 num_rows, GeneralMatrix *out)
	This function extracts a row-range of a GeneralMatrix and writes as a GeneralMatrix containing the same type of underlying matrix. More...
