说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

说明：  电压型逆变器供电永磁同步电动机传动系统的动态仿真(The voltage type inverter power supply of permanent magnet synchronous motor drive system dynamic simulation)

this paper desctibes one of new method in photovoltaic issues. nice information included

fingerprint recognition

leap frog algorithm for solving metaheuristic problems and shortening the path to find the most optimized path.

数字信号 ASK FSK PSK 在时域上是稀疏的(ASK FSK PSK digital signals in the time domain is sparse)

m-fsk modulation and de modulation

In this file you can find the rayleigh fading channel. you can use matlab to open it.

Fuzzy logic C & matlab code

说明：  用于求解高速球轴承的非线性方程组，输入主程序，用fsolve，可以直接解出来(Nonlinear equations used to solve high-speed ball bearings, input the main program, with fsolve, can be solved directly.)
