关于弹性力学问题的有限元Matlab程序,里面有主函数和子函数

in this program I have deduced dimension of iris data with PCA

偏微分数值解中，解双曲型方程的有限差分格式，会有色散和耗散现象，此程序就是做的这个

自己编写的近邻法算法，包括k近邻法、两分剪辑和重复剪辑、压缩算法。在文档中给出了一个简单的算法原理说明，详细参考边肇的《模式识别》。注：里面的分类线绘制算法存在一些问题，仅供大家参考修改。(The nearest neighbor algorithm written by myself, including k nearest neighbor, the two sub-editing and re editing, compression algorithm. The document gives a simple algorithm principle . The detailed explanation can be found in the book Pattern Recognition written by Bian Zhaoqi. Note: The line drawing algorithms have some problems, only for your reference.)

说明：  求解动态有限元方程，板式轨道过渡段动力响应分析源程序(Dynamic finite element equations to solve, slab track Dynamic Response Analysis of the transition source)

this is my code which i learnt in image processing lesson. it finds any geometric shape and draw black lines around it which stands on a white background. it could help how to find a shape for new learners in DIP

很好的一本书，适合初学者，尤其对想要用matlab实现与计算机互动的人很重要。(A good book is suitable for beginners, especially to want to use matlab and computer interaction people is very important.)
