说明：  模糊PID控制器设计源程序，已在matlab中运行通过，有良好的控制效果(Fuzzy PID controller design source, has been run by matlab, good control effect)

画图时，将图形局部放大，很实用的代码，以前上传过一个m文件，上传错误了，现修正。(When drawing the graphic enlarged, very practical code previously uploaded an m file upload error, now corrected.)

This MATLAB code computes the covariance matrix of a random variable

基础的BP神经网络应用。附有注释，适合初学，简单易懂。(basic utilities of BP neural networks.)

第06讲 MATLAB绘二维图数字图像处理课件-matlab语言基础，很适合做图像如理入门使 用系列(Digital image processing based on matlab language courseware), very suitable for image such as introduction to use series)

该损伤模型通过 商用有限元软件ABAQUS /Explicit 的用户子程序VUMAT 实现，并使用该模型对碳纤维增强环氧树脂 复合材料层合板在横向低速冲击作用下的损伤和变形行为进行预测分析． 数值仿真的结果与试验结 果进行了比较，吻合良好，验证了该模型的有效性．(Through coding user subroutine VUMAT of finite element software ABAQUS /explicit， and applied the model to an example，carbon fiber reinforced epoxy composite laminates under low velocity impact，the prediction for damage and deformation were good agreement with the experimental results．)

交互界面，检测图像中的直线，并计算交点、直线角度、长度、端点位置(Interaction interface, detects the straight line in the image, and calculates the intersection point, the straight line angle, the length and the end point position.)
