非常不错的QPSK在matlab中的仿真教程，文档中包含相关的所有代码(very good QPSK in the Matlab simulation Guide, the document contains all the related code!)

This is the image segmentation code. It uses built in fuction fcm to perform the image segmentation. It partition the images into seven clusters.

matlab 遗传算法GA，粒子群算法PSO,蚁群算法AS 前段时间上智能计算方法实验课上，自己做的程序。帖到这里，希望有人能改进它们，交流经验这样更有价值。 遗传算法解决最小生成树问题，PURFER编码。 粒子群算法做无约束最优化问题。 蚁群算法解决TSP问题。 如果有宝贵经验希望能交流一下，谢谢，呵呵(matlab genetic algorithm GA, particle swarm optimization PSO, ant colony algorithm for calculation of AS some time ago on the intelligent test classes, make their own procedures. Quote here, hope someone can improve them, and exchange of experience which is more valuable. Genetic algorithm to solve the minimum spanning tree problem, PURFER coding. Particle swarm optimization to do unconstrained optimization problem. Ant colony algorithm to solve the TSP problem. If there is hope to exchange our experience, thank you, He He)

说明：  小波神经网络的MATLAB程序 是一个通用的matlab程序。(Wavelet Neural Network MATLAB procedure is a common procedure matlab.)

说明：  用matlab做的，而且有图片和解释。我用了2个小时写的，虽然不太好，还是可以供大家参考的。(using Matlab done, but pictures and explanation. I spent two hours writing, though not very good, or to be available for reference.)

经济学的数值方法 配套例题以及习题答案的有关牛顿法 最速下降优化的部分。(Newtown methods)

说明：  用平面波展开法计算二维二组元圆柱散射体型声子晶体能带结构的matlab代码。(This matlab code uses PWE to calculate the band structure of 2-D phononic crystal with cylinder scatterer.)

绝对经典超全少见的matlab学习资料大全，尤其清华的那本非常不错，有了这些你就成为mablab高手。(Absolute classic ultra-wide learning materials matlab rare Guinness, in particular that of the Tsinghua very well, with these you become a master mablab.)

本书系统地介绍MATLAB 7.0的混合编程方法和技巧。本书既适合初学者自学，也适用于高级MATLAB用户，可作为高等数学、计算机、电子工程、数值分析、信息工程等课程的教学参考书，也可供上述领域的科研工作者参考。(This book systematically introduces MATLAB 7.0 mix of programming methods and techniques. This book not only suitable for beginners self-learning, also applies to high-level MATLAB users, can be used as advanced mathematics, computer, electronic engineering, numerical analysis, information engineering curriculum reference books are also available in these areas of research workers.)

说明：  利用物体的几何特征参数，和bp神经网络实现分类。(The use of the geometric characteristics of object parameters, and the realization of bp neural network classification.)
