应用matlab开发的ofdm源代码，其中和QAM调制方式做了比较，内含部分说明文档(Application development of OFDM matlab source code and QAM modulation which has done a comparison, contains some documentation)

butterworth filter for image enhancement

说明：  匹配追踪和正交匹配追踪的算法。用于时频分析算法。(mathing pursuit algorithm )

1.约束优化问题： minRosen(Rosen梯度法求解约束多维函数的极值)(算法还有bug) minPF(外点罚函数法解线性等式约束) minGeneralPF(外点罚函数法解一般等式约束) minNF(内点罚函数法) minMixFun(混合罚函数法) minJSMixFun(混合罚函数加速法) minFactor(乘子法) minconPS(坐标轮换法)(算法还有bug) minconSimpSearch2(复合形法) (Optimization problem correlation algorithm)

该代码为基于FCM-GRNN的聚类算法，MATLAB中处理神经网络类型(The code for the clustering algorithm based on the FCM-GRNN neural network types MATLAB processing)

说明：  基于小波变换的jpeg图像压缩编码算法的MATLAB实现(small wave transportation)

说明：  计算光纤模场分布和传播常数，输入模式的阶数，计算得到各类模式的模场分布。直接运行main，在其中修改参数，至少可以计算5层光纤结构。(Calculation of optical mode field distribution and propagation constant, the order input mode, calculated by various types of mode-mode field distribution. Direct run main, in which the modified parameters can be calculated for at least 5 layer fiber structure.)

实现bpsk的调制解调 ，有图，基于matlab仿真 (Achieve bpsk modulation and demodulation, a map)

Hypoplastic sand model

说明：  newmark 简单方法 简单的示例 简单易懂(The newMark simple method simple example is easy to understand)
