matlab绘制各种周期信号如正弦波等常用的信号，下下看吧吧吧。(matlab draw a variety of periodic signals such as sine wave signal, such as commonly used, under the under the bar and see it.)

介绍了线性规划方法，并有实力分析，附有matlab程序代码(Linear programming, and strength analysis with matlab program code)

SPWM inverter with Matlab/simulink

这是一个耗时巨长的程序，很费脑筋，所以大家一定要珍惜，希望对大多数人有所帮助，如有问题，可以联系我591805444（QQ）(This is a time-consuming giant long procedures, is very annoying task, so we must cherish, hope to most people help, if there is a problem, can contact my 591805444 (QQ))

说明：  球体重力异常曲线正演，加噪音后异常曲线，最小二乘反演(Gravity anomaly curve ball forward, plus the noise of abnormal curve, least-squares inversion)

基于PCA 和BP 神经网络的人脸识别方法是针对 PCA 方法中存在的高维数问题和它对未训 练过的样本识别率低的缺点而提出的。该方法在预处理的基础上，利用粗糙集对 PCA 降维处理后的人脸特征进行约简，提取其中分类能力强的特征，实现在识别精度不变的情况下，有效的去除冗余信息；然后将约简后的属性输入到神经网络进行规则提取，利用神经网络非线性映射和并行处理的特点，增强对人脸图像识别的泛化能力。实验证明，使用该方法在识别率上有一定的提高(Face recognition method based on PCA and BP Neural Network)

修正的canny算子进行边缘检测提取，具有高的检测率，精确的定位，明确的相应。(Modified canny operator to extract edge detection with high detection rate, accurate positioning and clear accordingly.)
