Detailed Description

template<class T = int, class ALLOC = std::allocator<T>>
class BFL::boost::numeric::ublas::zero_matrix< T, ALLOC >

A matrix with all values of type T equal to zero.

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