一个简单的相控阵超声波探伤及成像系统模型。现在可以模拟三种声波束的成像结果，适合理解超声波探伤原理。( 1 ：for Plane B-scan 2 : for Focused B-scan 3 : for Sector B-scan)

apcluster是发表在今年2007年Science上的一篇论文的代码实现,一种新的有效的聚类算法,(apcluster is published in Science this year, in 2007 a paper on the code, a new effective cluster algorithm,)

本文件是是我们组参加2013全国大学生数学建模的比赛论文，荣获全国2等奖，不信可以百度下，包括所有论文程序的附件，完整版，程序包括matlab的程序，有神经网络的程序，基于小波分析的程序，也有基于vissim交通流的仿真程序包！相当给力！程序阅读和说明都在上面！(This document is our group to participate in the 2013 national college tournament mathematical modeling papers, won the two prize, do not believe you can Baidu, the program includes all papers attachments, full version, matlab procedures, including procedures, a neural network program, Based on wavelet analysis procedures, there are also based vissim traffic flow simulation program package! Quite a force! Read the instructions and procedures are in it!)

matlab中实现tab的panel，也是从matlab论坛中得到的(implemented in matlab tab of the panel, is also derived from the matlab forum)

ofdm信道编码和译码的源代码，用matlab实现(OFDM channel coding and decoding of the source code, using Matlab to achieve)

说明：  一个很不错的PLS工具包 带gui界面 里面 有详细使用帮助。(pls gui)

说明：  matlab中一些重要的课件和资料，比较有用啊！(matlab courseware and some important information, more useful ah!)

说明：  灰预测，运用灰预测的MATLAB实现，建立模型，求解未来的预测值(gray modol)

经典的注水算法 可用来解决信道中质量好的信道多分功率，质量差的少分。(Classical algorithm can be used to solve the water quality channel multi-channel power, a smaller share of poor quality.)
