Detailed Description

template<class T, class ALLOC>
class boost::numeric::ublas::zero_matrix< T, ALLOC >

Changing values does not affect the matrix, however assigning it to a normal matrix will put zero everywhere in the target matrix. All accesses are constant time, due to the trivial value.

Template Parameters:

	T	the type of object stored in the matrix (like double, float, complex, etc...)
	ALLOC	an allocator for storing the zero element. By default, a standar allocator is used.
