说明：  非线性动力学控制理论中的相图和分岔图绘图代码(Drawing Code for Phase Diagram and Bifurcation Diagram of Nonlinear Dynamics Theory)

非高斯有色噪声中的谐波回复的方法研究，主要是SVD_TLS方法。(Methods of non-Gaussian colored noise harmonic restoration )

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.
