本文件内容是蒙特卡罗算法，主要是对一些被积函数难的多重积分进行估计，文档除了程序以外，还有详细的讲解，便于理解。(Contents of this document are the Monte Carlo algorithm, mainly for some of the integrand is difficult to estimate the multiple integration, documentation, in addition to the program, there are detailed explanations, easy to understand.)

说明：  基于matlab小波变换分解信号并重构算法过程分析及代码(Signal based on wavelet transform decomposition and reconstruction algorithm matlab process analysis and code)

计算一个混沌序列的Lyapunov 指数，可以直接把所需要计算的混沌序列输入，就可以得到所要的曲线和数值(Calculation of a chaotic sequence of Lyapunov index, can be directly calculated by the chaotic sequence required input, it can be to the curves and numerical)

很不错的matlab电子书籍，内有实例解析，值得推荐。(Matlab very good e-books, there are examples of analysis, worthy of recommendation.)

WALKER Human gait. This model, developed by Nikolaus Troje, is a five-term Fourier series with vector-valued coefficients that are the principal components for data obtained in motion capture experiments involving subjects wearing reflective markers walking on a treadmill. The components, which are also known as "postures" or "eigenwalkers", correspond to the static position, forward motion, sideways sway, and two hopping/bouncing movements that differ in the phase relationship between the upper and lower portions of the body. The postures are also classified by gender. Sliders allow you to vary the amount that each component contributes to the overall motion. A slider setting greater than 1.0 overemphasizes the characteristic. Can you see whether positive values of the gender coefficient correspond to male or female subjects?
