中文说明： 单变量Logistic非线性模型是最早，也是最经典的非线性模型，也是混沌理论的起源。一个简单的迭代公式：x(n+1) = lambda * x(n) * (1 - x(n)) 却能够迭代出意想不到的解雇，该程序包中branch为生成模型的分岔图，通过分岔图可以清楚地看到有周期进入混沌的过程;power为生成这一过程的功率谱；balancepoint是求解平衡点的几何图形表示；time_x为点移动的状态图。
English Description：
Non-linear multivariate Logistic model is the first and most classical non-linear model and the origins of chaos theory. A simple of Diego generation formula: x (n+1) = lambda * x (n) * (1-x (n)) is can Diego generation out unexpected of fired, the program package in the branch for generated model of points Cha figure, through points Cha figure can clearly to see has cycle entered chaos of process; power for generated this a process of power spectrum; BalancePoint is solution balance points of geometry said; time_x for points mobile of State figure.
