| 摘 要： | 在非对称、非正定满阵线性方程组的求解过程中,本文以高斯迭代为基础,提出一种残差优化的迭代法.该法在迭代收敛过程中,残差单调下降,大大缩短了线性方程组的求解时间.用该法替代直接解法,增大了求解方程组的阶数,缩短了计算周期,对复杂飞行器气动、隐身一体化优化设计具有重要的工程价值.该方法还可以广泛地推广到其它应用领域.

| Abstract: | To solve linear equation system with an asymmetric, nonpositive-definition and nonsparse coefficient matrix, a residual minimization method based on Gaussian iteration is proposed in this paper. By using the method, a rapid and monotone reduction of the residual could be achieved and the optimization efficiency could be increased for a design problem. The results of the demonstration problem shows the feasibility and applicability of the method. |
