针对主成分分析的很实用的程序，只需要把所掌握的数据带入，就可以获得一系列的数据，包括相关矩阵、载重、主成分贡献率等。(Principal component analysis and practical program, simply put into the master data, you can get a range of data, including the correlation matrix, load, principal component contribution rate.)

pca的matlab程序，提取特征值大于1的主成份(pca matlab program, the main ingredient extracted with eigenvalues ​ ​ greater than 1)

字符识别，较为入门的字符识别程序，基于MATLAB。适合入门(Character recognition, character recognition program is started, based on the MATLAB. Suitable for entry)

Matlab code for speech recognition

光伏仿真及mppt（P Q） 有论文参考，可对照论文一步一步搭仿真(光伏仿真及mppt（P Q） 论文对照)

基于粒子群优化算法的ELM，很稳，自己写的亲测可用(ELM based on particle swarm optimization algorithm)

SIMULINK® MODEL FOR SIMULATION OF A 14-BIT PIPELINE ADC(SIMULINK ? MODEL FOR SIMULATION OF A 14-BIT PIPELINE ADC)

matlab,simulink视频,并有播放器(vidio of matlab,simulink)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

说明：  纯水的负折射率计算，使用LH模型，适用频率范围小于3THz，可用于计算雨滴衰减模型(Negative refractive index of pure water calculated using the LH model for the frequency range is less than 3THz, can be used to calculate the rain attenuation model)
