一本极少非线性有限元基本理论和程序实现的经典教材(An intruoduction nonlinear finite element method )

信号的相关性是信号本身很重要的性质，本程序就是求随机信号的自相关性。(Signal is the relevance of the signal itself is very important properties, this procedure is for the random signals between autocorrelation. )

光伏逆变器的仿真文件，带Boost，可以很好的仿真，用于公司的实际样机仿真中，效果还不错(PV inverter simulation file with Boost, good simulation for the actual prototype simulation results were pretty good)

Subcarrier allocation in mimo-ofdma

kpca原始程序和小波去噪部分，用于数据降维和特征提取比较实用(kpca part of the original program and wavelet denoising for data dimensionality reduction and feature extraction more practical)

由给定高斯线型半高全宽，与洛伦兹线型半高全宽，计算对应的归一化的Voigt线型。(use the FWHM of Gaussin profile and Lorentz profile to caculate the voigt profile which is normalized by energy.)

特征提取，主要应用matlab对图像的特征进行提取，获得一些精度。(tezhengtiqu)

说明：  完整详细的介绍OFDM系统源码，保证代码能运行。(OFDM system described in detail the full source code, to ensure that the code can run.)

matlab仿真微分方程，分别用欧拉法，改进欧拉法，龙格库塔法，四阶adams显式隐式算法对比精度。(matlab simulation of differential equations, respectively, with Euler, improved Euler method, Runge-Kutta method, fourth-order implicit algorithm adams explicit comparison accuracy.)

This is a demo code to illustrate application of blind compressive sensing framework to recommender system design (to predict users choice for items).
