Functions
template<TLAPACK_SMATRIX matrix_t, TLAPACK_SVECTOR alpha_t, TLAPACK_SVECTOR beta_t>
int	tlapack::multishift_qz (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, FrancisOpts &opts)
	multishift_qz computes the eigenvalues of a matrix pair (H,T), where H is an upper Hessenberg matrix and T is upper triangular, using the multishift QZ algorithm with AED.
