【Abstract】 The relationship between error vectors resulted from mini_max solution and least square solution of an overdetermined linear equations is discussed. Some interesting properties of maxi_deviation points in the sense of Tchebycheff approximation are given. Finally, a new direct_modifying approach to decrease maxi_deviations is proposed and can be used in system recognition, parameter estimating and signal processing, etc. 更多还原
