Solving knapsack with MATLAB

用lms分类器实现了比较准确的分类，同时给出了实验的结果。运行正确，直接调用程序即可。(Lms classifier achieved with the more accurate the classification of the experimental results are given. Running correctly, you can directly call the procedure.)

平滑信号程序源代码，可用于模态分解，EMD,LMD等模态分解方法都能用到(Smooth signal program source code. . . For EMD)

说明：  基于直方图处理的MATLAB人脸识别算法(Matlab face recognition algorithm based on histogram processing)

This is a MATLAB Simulation file in which Predictive current control(PCC) modulation method for a Full Bridge (2-legs) inverter has been done.The load is a single Phase R_L.

轴承故障谱峭度分析，打开直接运行，包含包络谱分析(Bearing failure analysis of spectral kurtosis, open directly run, including envelope spectrum analysis)

光伏接入配电网的影响计算，主要是网损计算，适合新手学习使用(The impact of access to distribution grid PV calculation, mainly net loss calculation, suitable for novice learning to use)

黄金分割法求极小，返回值fm为函数极小值，tm为极小值点，f为给定函数，t为函数变量，[a,b]为变量t的搜索区间(Golden section method is extremely small, the return value for the function fm minimum, tm for the minimum point, f for a given function, t for the function of variables, [a, b] for variable search interval t)

利用游程编码和哈弗曼编码实现灰色图片的压缩和解码，压缩比可达15倍(Using run-length encoding and Hafu Man Coding and decoding of gray image compression, the compression ratio up to 15 times)

说明：  先对图像均衡化 增强对比度 加噪声 然后分别进行空域和频域滤波(First, the contrast enhanced image equalization plus noise and then separate airspace and frequency domain filtering)
