平均标准偏差，一个计算用的Matlab小程序，希望大家喜欢(The average standard deviation, a calculation using a small Matlab program, I hope everyone likes)

加窗设计FIR滤波器，其中有矩形窗和哈明窗两种窗的加窗方法及频谱分析(Windowed FIR filter design, including rectangular window and Hamming window of Windows and both methods and spectral analysis)

本程序主要是用matlab对曲柄摇块机构的计算并输出图形。通过本程序可以计算出曲柄摇块机构的位移、角速度和角加速度并输出其图形，还可以输出曲柄摇块机构的运动仿真图(This procedure is mainly used matlab for crank block body shake Calculation and output graphics. Through this program can calculate the crank block body roll displacement, angular velocity and angular acceleration, and output the graphics, you can also shake the output crank kinematic simulation block diagram)

包含十种经典的软件滤波的说明，以及其中8种滤波的例子，都是带的学生写的，并且附带测试报告。(Contains ten kinds of classic filtering software descriptions and examples of which eight kinds of filtering are written with students, and with a test report.)

区域生长算法，一个老美写的，算法写的相当巧妙，需要花点时间好好看下。(Region growing algorithm, written by an old America, the algorithm is quite clever to write, take time to properly see next.)

用两种向量化和一种循环的思路计算水仙花数，并给出所需时间比较 水仙花数是指一个三位数,其各个数的立方和等于该数(Quantified in two and a loop to the idea of calculating the number of daffodils and narcissus are given the time required for comparison is a three-digit number, the individual cubes, and equal to the number of)

心电信号的hurst指数算法，利用该指数可以用于区别正常心电信号和窦性房型早搏的心电信号(Hurst index ECG algorithm, using the index can be used to distinguish between normal sinus ECG and ECG chamber premature)

model of Inverted Pendulum

- Stone column play important role in infrastructure, improving soft soil. The behaviour of stone column, however, remains far well understood
