摘要
系统病态性问题在测量数据处理领域是常见的,具有许多种解算方法。迭代法是其中的一种。通过分析病态矩阵的性质,基于谱修正迭代法,构造了一种迭代算法,实例表明:该算法是有效的,提高了迭代速度,具有实际意义。
Ill-conditioned problems are common in measurement data processing with many kinds of solutions.Iteration method is one of them.The paper discusses the property of ill-conditioned matrix,and then introduces an algorithm based on iteration method by correcting characteristic value.An example shows that the algorithm is effective,it can improve the iteration speed and have practical significance.
