利用保留交叉验证(hold-out)的特征选择，有筛选排序的功能，并最终可以输出对应特征下标。(The use of cross-validation reserved (hold-out) feature selection, there is sort of filtering function, and eventually you can output the corresponding feature subscript.)

为超级电容设计的双向充电 使用back-boost电路，含电流换向时切换控制方式(Designed for super capacitor two-way charge to use the back- the boost circuit, current commutation switch control mode)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

this is the code to illustrate movement(image processing in matlab

基于matlab平台的lpc谱提取代码，对语音信号处理有重大作用(Based the matlab platform lpc spectrum extract the code, have a significant role in the speech signal processing)

光纤LP模式,光纤模式计算，纤芯模式，有效折射率(Fiber LP mode, fiber mode calculation, fiber core mode, effective refractive index)

这是压缩感知领域，一个重构算法--子空间追踪方法，此方法是基于OMP之后的改进算法。(This is a compressed sensing area, a reconstruction algorithm- subspace tracking methods, this method is based on the OMP after the improved algorithm.)

说明：  语音识别HMM隐马尔可夫全过程的matlab程序，运行测试能出结果，希望对你们有用，实在没点数才把自己压箱底的东西拿出来,呜呜(HMM speech recognition, Hidden Markov whole process of matlab program, run the test to the result, I hope helpful for you, it is only then did their own pressure points things bottom out, whining)
