超松驰迭代法，用于快速求解线性方程组，可按每行注释理解算法原理，可自行调整松弛因子（一般建议1.2左右有良好效果）(The super relaxation iteration method is used to solve the linear equations quickly. It can understand the algorithm principle according to each row annotation, and can adjust the relaxation factor by itself. (generally speaking, 1.2 has good results).)
