matlab调用ansys的例子，适合初学者。(matlab call ansys example, suitable for beginners.)

这是计算分维数的分形程序，经检测能完美运行，效果很好。(This is dimensions calculation fractal program, after testing can perfect operation, the effect is very good. )

粒子群改进算法，有助于学生学习,可以在此基础上改进(Improved particle swarm algorithm to help students to learn, you can improve on this basis)

多元统计分析在超声检测回波信号处理中的应用(Multivariate statistical analysis of ultrasonic echo signal detection processing applications)

内容丰富的Matlab数值计算与编程教程，300多页，推荐(Rich content of the numerical simulation with Matlab programming tutorial)

说明：  通过实际采集到的数据，数显通过数据预处理，进行不良数据的清洗，然后通过PCA降维，k均值聚类提取运动学片段，建立运动学片段库，通过随机策略提取运动学片段构成汽车行驶工况。(Through the actual collected data, the digital display cleans the bad data through data pretreatment, and then extracts the kinematics fragments through PCA dimensionality reduction, K-means clustering, establishes the kinematics fragments library, and extracts the kinematics fragments through random strategy to form the driving conditions of the vehicle.)

混沌系统的简介以及神经网络的MATLAB实现(Chaotic system and the neural network of MATLAB)

这个程序检测出了图像中的直线,而且用绿色标出直线,直线断电用+表示,并且用不同颜色标出了最长的直线(this procedure detected the image straight, and marked with a green line, a straight line with power outages, and with different colors marked the longest line)

数米粒，matlab编程实现图片中米粒边缘的提取，然后实现连通域的标记，最后统计连通域个数(Number of rice, matlab programming rice extract picture edges, then realize marking connected domain, the number of connected domains final statistics)

ode45源文件，貌似还不错哦，为什么要那么长(ode45 source file, looks like bad Oh, why did it take so long)
