Functions
template<TLAPACK_MATRIX matrix_t, TLAPACK_VECTOR vector_t, bool >
int	tlapack::lahqz_shiftcolumn (const matrix_t &A, const matrix_t &B, vector_t &v, complex_type< type_t< matrix_t > > s1, complex_type< type_t< matrix_t > > s2, type_t< matrix_t > beta1, type_t< matrix_t > beta2)
	Given a 2-by-2 or 3-by-3 matrix pencil (A,B), lahqz_shiftcolumn calculates a multiple of the product: (beta2*A - s2*B)*B^(-1)*(beta1*A - s1*B)*B^(-1)*e1.
