Data-preprocessing

说明：  计算温度场分布的程序，希望对有关人员有所帮助,基于matlab(Calculated temperature distribution of the procedures in the hope the officers concerned be helpful, based on matlab)

说明：  用正弦波叠加的方式生成一个最简单的 Rayleigh Fading Process ，具有 Doppler Frequency 。(Sine wave superimposed with the easiest way to generate a Rayleigh Fading Process, with Doppler Frequency.)

implementation of jpeg compression

实现bpsk信号的调制和解调，加噪声之后的解调(The modulation and demodulation of BPSK signals are realized)

通过均值聚类实现四类数据的分类，一直在用(means clustering )

优化问题是工业设计中经常遇到的问题,许多问题最后都可以归结为优化问题. 为了解决各种各样的优化问题,人们提出了许多优化算法,比较著名的有爬山法、遗传算法神经网络算法等. (Optimization problem is often encountered in industrial design, many problems can be attributed to the last optimization problem in order to solve a variety of optimization problems, many optimization algorithms have been proposed, relatively well-known climbing method, genetic algorithm neural network algorithm.)

说明：  jaya算法，MATLAB程序，需要的可以自行下载(aya algorithm, matlab program, you can download what you need,)

说明：  信号实验常用的simulink模型和mfile,可直接在matlan下运行。(Simulink signals commonly used in experimental models and mfile, can be run directly in matlan.)
