Functions
template<TLAPACK_SMATRIX matrix_t, TLAPACK_VECTOR vector_t>
int	tlapack::ungr2 (matrix_t &A, const vector_t &tau)
	Generates an m-by-n matrix Q with orthonormal columns, which is defined as the last m rows of a product of k elementary reflectors of order n.
template<TLAPACK_SMATRIX matrix_t, TLAPACK_VECTOR vector_t, TLAPACK_WORKSPACE work_t>
int	tlapack::ungr2_work (matrix_t &A, const vector_t &tau, work_t &work)
	Generates an m-by-n matrix Q with orthonormal columns, which is defined as the last m rows of a product of k elementary reflectors of order n.
template<class T , TLAPACK_SMATRIX matrix_t, TLAPACK_VECTOR vector_t>
constexpr WorkInfo	tlapack::ungr2_worksize (const matrix_t &A, const vector_t &tau)
	Worspace query of ungr2()
