3D-DCT

分形维数计算，差分盒计数法，编译过，可以用(chafen)

说明：  本程序是一个采用背景差分的运动目标检测方法(This program is a moving target using the background difference detection method)

主要的粒子群优化方法的matlab实现,粒子群优化算法的主要理论的实现方法(the methods of the PSO)

this code is solution of optimal control

新型调制技术 OFDM matlab 代码(The new modulation technique OFDM matlab code)

实现BPSK调制仿真的性能参数计算，功率谱的绘制，非常实用！(BPSK modulation to achieve the performance parameters of the simulation calculation, the power spectrum of the draw, very useful!)

说明：  利用MATLAB可以产生各种形式的随机数，进行随机解决一些实际问题（系统的寿命、重积分、预测公司经营）(using MATLAB can produce various forms of random numbers, random solve some practical problems (system of life, re-integration, the company forecast operating))

利用MATLAB实现的最小包围矩形算法，精简实用(MATLAB implementation of the minimum bounding rectangle algorithm)

运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)
