摘要
对于位移反分析对应的线性代数方程组，本文说明了其解可能出现不稳定；根据线性方程组系数矩阵的奇异程度，介绍了合适的求解方法，最后，提出了一种有效的确定任意矩阵奇异值的迭代方法。
This paper demonstrates that the solutions may be unstable for the corresponding system of linear algebuaic equations of the back analysis of displacements. And thesuitable method for obtaining solutions are introduced,according to the singular degree of coefficient matrixes of linear eqtiations.Finally,an effective iterative method is proposed fordetermining the singular values of arbitrary matrixes
