摘要
文章简述了矩阵奇异值分解的理论与性质,着重研究了其解算病态方程的思想、特点和存在的问题,并用实例进行了计算,最后推荐在数据处理时可使用奇异值分解法.
This paper describes breifly the theory and character of singular value decomposition of matrix, emphasizes the idea, characteristic and existing problems of solving the ill-conditioned equations, and calculation has been conducted by practical examples. Finally the singular value decomposition method is recommended in data processing.
