说明：  基于石油钻井神经网络PID仿真器模型，该模型验证了该算法的可行性和有效性(BTF simulink fangzhen)

小波包分析提取振动信号中的特征频率，仿真效率很高的，采用累计贡献率的方法。( Wavelet packet analysis to extract vibration signal characteristic frequency, High simulation efficiency, The method of cumulative contribution rat.)

收集的一组跟噪声产生以及消除、衡量消噪性能指标的MATLAB仿真源代码，每个文件夹下都附有对该代码的注解！(gathered with a group and the elimination of noise, the weighing-noise performance indicators MATLAB simulation source code, Each folder with all of this code notes!)

获得一个二部图（两个部的顶点数要求一致）的最大匹配集，用于分配等问题的求解(get the maxinum_peipe )

yuv格式数据图像显示，420格式，yuv转rgb(yuv geshi shuju tuxiang xianshi，420 geshi， yuv to rgb)

压缩感知，华东师范大学陆吾生教授讲义的程序(Compressed sensing, East China Normal University Professor Lu Wusheng handout program)

Rayleigh无线衰落信道的MATLAB仿真。 (Rayleigh fading channel wireless MATLAB simulation.)

用于图像质量评价的ssim程序，用以对图像的质量进行客观评价，评价结果更接近主观感受(Ssim for image quality assessment procedures for an objective image quality evaluation, evaluation results are closer to the subjective feelings)

通量数据足迹分析，可查看最大贡献源区。以及数据质量分级(analysi footprint)

电压前馈正反馈的孤岛检测方法。无盲区检测速度快，(Voltage feedforward positive feedback islanding detection method. No blind spot detection speed,)
