仿真效率很高的，包括AHP，因子分析，回归分析，聚类分析，使用大量的有限元法求解偏微分方程，加入重复控制，双向PCS控制仿真，真的是一个好程序，采用累计贡献率的方法，有较好的参考价值。- High simulation efficiency, Including AHP, factor analysis, regression analysis, cluster analysis, Using a large number of finite element method to solve partial differential equations, Join repetitive control, Two-way PCS control simulation, Really is a good program, The method of cumulative contribution rate There are good reference value.
