这里是初学者在学习使用MATLAB过程中会经常遇到的问题。(Here are a beginner in learning to use MATLAB process will often encounter problems.)

THIS IS 2 MATLAB CODES OF SIGNAL PROCESSING

Program for relay activation via parallel port

模拟退火算法(Simulated Annealing,简称SA算法)是模拟加热熔化的金属的退火过程，来寻找全局最优解的有效方法之一。(Simulated Annealing algorithm (Simulated Annealing algorithm, hereinafter referred to as SA) is simulation heating the molten metal the Annealing process, to search for the optimal solution of one of the effective method. )

说明：  基于混沌的图像加密，用于MATLAB的图像加密，对图像进行置乱。。。。。。。。。。。。。。。(Chaos-based image encryption algorithm implement by matlab)

说明：  MATLAB的轴承故障时域特征和频域特征提取(Bearing fault time domain feature and frequency domain feature extraction)

对摄像的标定进行模拟，来分析误差对结果的影响，来确定标定的对最后结果的影响。(To simulate camera calibration to analyze the impact of the error on the results to determine the impact on the final outcome of the calibration.)

数字通信中的锁相环（PLL）完整程序，包括噪声处理，可用于GPS的的跟踪和捕获(the matlab code of PLL ,including how to deal with the noise ,which can be used to acquiring and tracking on GPS)

二维经验模式分解（BEMD）程序，可用于图像分解 (Bidimensional Empirical Mode Decomposition)

离散傅里叶变换，即DFT, 注意：FFT在matlab里有现成的函数可以用，它只是DFT快速实现的一种方法而已。(DFT： Discrete Fourier transform. )
