中文说明：应用背景近年来，预条件迭代法因为可以很好的解决迭代时解的收敛速度非常缓慢这一情况，越来越受到很多学者的关注，不同的预条件矩阵的解的收敛速度影响也不同，众多学者试图找到更优的预条件矩阵。 关键技术包含了GAOR、GMTS以及MAOR三种预条件迭代法的数值算例程序，可以按照自己的预条件矩阵进行修改，给定参数值，运行便可得到未预条件和预条件迭代矩阵的谱半径值。
English Description：
Application backgroundIn recent years, preconditioned iterative method for solving the iterative convergence rate can be a good solution is very slow this situation, more and more attention of many scholars, the convergence speed of the preconditioned matrix is different, many scholars try to find better pre condition matrix. Key TechnologyContains GAOR, GMTS and MAOR values of three kinds of preconditioned iterative method for the example program, can be modified according to their pre condition matrix, the given parameter values, the operation can be obtained without pre conditions and the spectral radius of preconditioned iterative matrix.
