说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

此代码为混沌相空间重构的代码，对学混沌学的朋友很有处(This code is a chaotic phase space reconstruction of the code, the school is very chaotic at the school' s friends)

jit精益生产的论文，很经典的。毕业答辩的优的哈(jit lean production of paper, very classic. Ha excellent graduate reply)

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)

此程序主要是根据已知条件，精确绘制两椭圆纯滚动啮合(This program is mainly based on the known conditions, precise drawing two oval pure rolling engagement)
