自己编写的旋转算法，没有用imrotate函数(havne t use the function imrotate of matlab)

说明：  该代码实现了著名的EM算法，清晰地演绎了E与M步的实现过程，相信对初学者非常有益。(The function of this code is to implement the famous EM algorithm.The E and M proceduce has been implemented indepently and clearly. It is very useful for beginners.)

随机快速算法与确定性快速算法的比较,可设置数组大，小包含有实验报告(Fast Algorithm for Stochastic Fast Algorithms and certainty, you can set an array of big and small contain Experimental Report)

这个是短时傅立叶变换程序,希望对大家有用了!(This is a short-time Fourier transform procedures in the hope that it may be useful right!)

The purp ose of this Primer is to help you b egin to use MATLAB. It is not intendedto b e a substitute for the User s Guide and Reference The purpose of this Primer is to help you begin to use Matlab.The Primer can best be used hands-on. You are encouraged to work at the computer as you read thePrimer and freely exp eriment with examples. This Primer, along with the on-line helpfacility, usually suce for students in a class requiring use of MATLAB
