电力系统专业本科生可以看下，用于计算三机九节点系统的潮流(calculation of the power flow)

里面包含了步态识别的整一套流程的代码实现，包括从视频流里面提取图片帧，背景建模，提取运动目标（运动检测），形态学处理（膨胀与腐蚀，连通性检测），归一化大小，步态能量图的构建，主成分分析（PCA）降维,线性判别分析（LDA）分类等等功能的代码实现。均通过测试。(Contains the gait recognition of the whole process of a set of code, including the extraction and picture frames from the video stream, and background modeling, extract the moving object (motion detection), morphology processing (expansion and corrosion, connectivity), normalized size, gait energy diagram construction, principal component analysis (PCA) dimensionality reduction and linear discriminant analysis (LDA) classification code implementation and so on functions. All pass the test.)

this code is simple and usful code it is a matlab code that optimize PID parametrs using Generic Algorithm

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0, i.e. it returns the vector A=(a,b,c,d,e,f). To convert this vector to the geometric parameters (This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.
