说明：  求解简单微分方程。模拟双摆运动并附简单说明材料。(For animation, the program uses Matlab s normal plot command combined with the drawnow command. It is based on the ode45 solution of the corresponding differential equations. Comprehensive documentation is provided, including a sketch of the most important steps of how to derive the equations of motion. A simple Mathematica notebook contains all of the manipulations. )

Matlab code that implements Runge-Kutta Method in the context of Differential Codes.

说明：  本程序为EMD（经验模态分解算法）用于MATLAB的M文件，内含EMD分解所需的三次样条插值算法(This procedure for the EMD (empirical mode decomposition) for the MATLAB M-files containing the required EMD decomposition of cubic spline interpolation algorithm)

说明：  M文件与程序调试 M-files and program debugging(M-files and program debugging)

利用PC上的声卡作A/D采样的MATLAB程序(On the use of PC sound card for A/D sampling of the MATLAB program)

本程序主要利用小波分析的mallat算法实现谱分析的功能(The main advantage of wavelet analysis procedure mallat function of spectral analysis algorithms)

本代码为牛顿下山法求解非线性方程组。其调用格式为[r,m]=mulDNewton(F,x0,eps) 其中F:非线性方程组，x0：初始解，eps：解的精度；r：求得的一组解，n：迭代步数。(The code for Newton' s method for solving nonlinear equations. Its call format [r, m] = mulDNewton (F, x0, eps) where F: non-linear equations, x0: initial solution, eps: solution accuracy r: obtain a set of solution, n : the number of iterative steps.)
