Detailed Description

template<typename T_value>
class HLIB::BLAS::Vector< T_value >

defines basic interface for vectors

\detail Standard vector class in linear algebra routines. It holds a reference to a memory block, which is controlled by this vector, e.g. if the vector is gone or resized, the memory block is also gone.
