摘要
Drawing upon subroutines HQRII and SHQRII, the most efficient FORTRAN codes available to solve the eigenproblem for dense real symmetric matrices, we developed a new FORTRAN program, named HQRII1. It is considerably more accurate than the above mentioned programs and runs on a VAX-11/780 computer 16, 19 and 23 percent faster than SHQRII for matrices of order 100, 150 and 200, respectively.
