说明：  基于GM算法和QR分解实现的稳健奇异值分解算法，通过该算法可以获取一个数居阵的稳健方差－协方差阵。在该稳健方差－协方差阵上可以进行诸如，稳健主成份分解、稳健聚类、稳健因子分析等操作。
(GM based on QR decomposition algorithm and the realization of the stability of singular value decomposition algorithm, the algorithm can be accessed through a number of UN-array sound variance- covariance matrix. In the robust variance- covariance matrix can be carried out, such as, robust principal component decomposition, robust clustering, robust operation, such as factor analysis.)
