| Abstract: | Methods for determining the correct solution of Bancroft-Algorithm are discussed and the new robust Bancroft-Algorithm based on the residuals of Lorentz inner product equation is developed to avoid frequently square root computing.In order to improve numerical stability and reduce memory space cost,orthogonalization algorithm is introduced.The stimulation experiment indicates that the new robust Bancroft-Algorithm has the same anti-outlier effect with the old one,but reduces the time cost by a factor about 30%. |
