Detailed Description

template<typename T>
class Matrix< T >

The abstract base class for matrices; provides size/shape and element access.

Matrix<T> is the absolute bare bones interface to a linear algebraic matrix. It provides an interface to size and shape, and an interface to obtain constant elements (thus, no guarantee of write-ability is made). Concrete classes may be derived from Matrix<T>, or from derived classes. Methods for obtaining submatrices are currently commented out because G++ 3.3 did not implement covariant return types (5/20/04).
