Detailed Description

template<std::size_t Rows, std::size_t Cols>
class tvmet::loop::gemv< Rows, Cols >

class for matrix-vector product using loop unrolling.

using formula

$M\,v$

Example:

 template<class T, std::size_t Rows, std::size_t Cols>
 inline
 void
 prod(const Matrix<T, Rows, Cols>& lhs, const Vector<T, Cols>& rhs,
  Vector<T, Rows>& dest)
 {
   for (std::size_t i = 0; i != Rows; ++i) {
     dest(i) = tvmet::loop::gemv<Rows, Cols>().prod(lhs, rhs, i);
   }
 }
