Functions
template<TLAPACK_CSMATRIX matrix_t, TLAPACK_VECTOR alpha_t, TLAPACK_VECTOR beta_t>
int	tlapack::lahqz (bool want_s, bool want_q, bool want_z, size_type< matrix_t > ilo, size_type< matrix_t > ihi, matrix_t &A, matrix_t &B, alpha_t &alpha, beta_t &beta, matrix_t &Q, matrix_t &Z)
	lahqz computes the eigenvalues of a matrix pair (H,T), where H is an upper Hessenberg matrix and T is upper triangular, using the single/double-shift implicit QZ algorithm.
