Detailed Description

template<typename Data>
class Util::Matrix< Data >

Two-dimensional array container template (abstract).

An Matrix object A is a two-dimensional array in which the operator A(i, j) returns a reference to element in column j of row i.

The memory for a Matrix is stored in a single one-dimensional C array, in which each row is stored as a consecutive block.

Class Matrix is an abstract class because it cannot allocate memory. Concrete subclasses include DMatrix and FMatrix.
