Detailed Description

template<class _Vector>
class LinBox::VectorStream< _Vector >

Vector factory This is an abstract base class that generates a sequence of vectors in a generic way. Typical uses would be in tests, where the same test might be run on a sequence of random vectors or on e_1, ..., e_n.

Public Types
