simple matlab programs

说明：  利用重标极差法计算Hurst指数，里面包含实现这一操作的子程序(Calcultate the Hurst)

MATLAB是一门计算机编程语言,取名来源于Matrix Laboratory,本意是专门以矩阵的方式来处理计算机数据,它把数值计算和可视化环境集成到一起,非常直观,而且提供了大量的函数,使其越来越受到人们的喜爱,工具箱越来越多,应用范围也越来越广泛 (MATLAB is a computer programming language, name comes from Matrix Laboratory, is meant to the Matrix of the special way to deal with the computer data, it put the numerical calculation and visual environment integration to together, very intuitive, but also provides a lot of function, make it more and more popular, more and more toolbox, application more and more widely )

说明：  Canny算子 Canny 算子是一种比较新的边缘检测算子，具有很好的边缘检测性能，得到了越来越广泛的应用。(Canny operator Canny operator is a relatively new edge detection operator, has good edge detection performance has been more widely used.)

控制系统中PID分数阶控制系统MATLAB工具箱(MATLAB Toolbox for PID Fractional Order Control System)

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”。例如6=1＋2＋3.编程 　　　 找出1000以内的所有完数。 (If a number is just equal to the sum of its factors, this number is called &quot End of a few.&quot For example 6 = 1+2+3. Programmatically find all finished within a number of 1000.)

这是基于MATLAB的几个基本小例子，其中包括bar,zhendh,zhidianyundong等功能的实现。(This is based on several basic small example of MATLAB, including the bar, zhendh, zhidianyundong functions implementation.)

二维声波正演程序！规则网格的时间空间二阶波动方程有限差分正演，matlab编写！！(Two-dimensional wave medling program! matlab prepared! ! Forward seismic acoustic source)

该文件为一个仿射非线性系统控制Matlab_simulink仿真，其中包含完全精确线性化和局部精确线性化的仿真模型，还有word实验报告，涉及非线性控制的同学可以参看一下(The file is a system control Matlab_simulink affine nonlinear simulation, which includes completely accurate linear and precise partial linearization simulation model, as well as word lab reports, involving nonlinear control students can see what)

说明：  这是多重信号分类的经典算法，仔细阅读，希望有所帮助，欢迎各位下载！(This is a classic multiple signal classification algorithm, carefully read, I hope be helpful, to welcome you all to download!)
