建立一个20结点的SW/NW小世界网络,可以调整参数建立其他的小世界网络(build a SW/NW small world net with 20 points，you can build other small world net by change the parameter )

利用两点距离计算经纬度的matlab程序，欢迎交流。(use latitude and longitude distance calculation procedures of Matlab, welcomed the exchange.)

本程序是本人根据人脸识别PCA改进的，用于掌纹识别，是学习PCA特征提取的很好的学习资料。(I based this program is to improve the face recognition PCA for palmprint identification, PCA feature extraction is to learn a good learning materials.)

具有分布荷载的超静定梁分析,这是一个非常典型的例子。(Analysis of statically indeterminate beam with distributed load。)

matlab从入门到精通，想学matlab的朋友可以下载下来参考(matlab from entry to the proficient, want to learn matlab friends can download reference)

说明：  利用粒子群优化算法对支持向量机中的核函数参数和惩罚参数进行优化是非常有效的手段，可以大大提高鲁棒性。实际过程中读者可通过下载我上传的代码，简单进行修改和阅读附件论文即可快速掌握相关方面的知识，快速使用这一方法。(Particle swarm optimization (PSO) is a very effective method to optimize the kernel function parameters and penalty parameters of SVM, which can greatly improve the robustness. In the actual process, readers can quickly grasp relevant knowledge and use this method by downloading the code I uploaded, simply modifying and reading the attached paper.)
