说明：  利用MATLAB实现模拟退火算法计算商旅问题(Use MATLAB to achieve simulated annealing algorithm Business Problems)

说明：  牛顿-拉夫森迭代方法是解非线性方程非常著名也是比较有效的方法之一，如果离初值近，收敛速度很快。(Newton- La Fusen iterative method for solving nonlinear equations is well-known effective method is one of, if the initial value from the past, the convergence is fast.)

We model the hunt as a game of three explicit stages: the stalk, the attack, and the subdual. We implemented this model in Matlab to simulate a velociraptor hunting a thescelosaurus and an African lion hunting a gazelle.

Hurst指数是描述非函数长周期的重要指标。它有别于传统单位根检验，可以发现时间序列存在的超长周期性，可以用于判断市场风险，但运算相当繁琐，单独利用Excel计算费时又费力，作者在充分理解Hurst指数内涵和应用的基础上，利用Excel的宏语言VBA编写宏程序轻松实现Hurst指数的计算，通过这一工作也希望能使Hurst指数能够得到广泛的应用。(Hurst index is to describe the function of the long period of non-important indicator. It is different from the traditional unit root tests, time series can be found in the presence of the long periodicity, can be used to determine market risk, but the operation rather cumbersome, separate consuming and laborious calculations in Excel, the authors fully understand the meaning and application of the Hurst exponent based on the use of Excel macros written in VBA macro language easily Hurst index calculation, also hopes to make this work through the Hurst exponent can be widely used.)

这段代码主要是实现二阶理想高通滤波器，本段代码全部用MATLAB语言实现的。(This code is to achieve the ideal second-order high-pass filter, the above code to achieve the full use of the MATLAB language.)
