PSO算法简单、易实现、计算量小，而且PSO 对初始点依赖性不大，具有更强的全局优化能力，也能较快的的收敛于可接受解。这是改进的pso,请多多指教。(PSO algorithm is simple, easy to realize the advantages of a small amount of computation and computational efficiency, and PSO dependence of the initial point, with stronger global optimization capability, but also faster convergence to an acceptable solution. This improved pso, exhibitions)

说明：  实现多通道后滤波技术，即经典的ZK算法，支持两路以上麦克风阵列的通道。(After the implementation of multi-channel filtering technique. Absolute classic.)

说明：  很好用的小波分解程序，简单，对初学者很有帮助。(Nice wavelet decomposition program, for beginners helpful.)

matlab从入门到高级进阶的必备好书，看了以后，希望对大家学习matlab有很高的提高！(matlab from entry to senior advanced essential books, looking after, in the hope that everyone has a very high learning matlab improve!)

光学字符识别，是matlab代码，简单易懂，有详细的注释(Optical character recognition, it is easy to understand and matlab code with detailed notes)

说明：  计算球形壳层纳米颗粒的散射问题，包括散射系数矩阵，消光系数，吸收系数等。源程序用Matlab编写，方便学习调试(Calculate the scattering of spherical shell nanoparticles, including the scattering coefficient matrix, extinction coefficient, absorption coefficient. Source code written using Matlab to facilitate learning debugging)
