用matlab读入各个通道载荷数据，计算最大幅值应力，并保存。没有次数。(max load )

图像分割的matlab代码，运行效果很好的。(Image segmentation matlab code, run very good.)

通信系统中的信号调制与解调技术，对信号比特流进行8QAM信号调制与解调的matlab仿真。(Communication system signal modulation and demodulation techniques for signal simulation matlab 8QAM bitstream signal modulation and demodulation.)

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.)

Multi-shift CGLS solves the systems of linear equations (A *A+TAU(I)*EYE(N))*X(:,I)=A *B (I=1:L) for X with the multishift CGLS algorithm. The right hand side (column) vector B must have length M, where the coefficient matrix A is M-by-N. TAU is a vector of reals (the shifts) of length L. For a short demo run main.m
