将采用训练函数 traingdx 和“提前停止”相结合的方法来训练 BP 网络，以提高 BP 网络的推广能力(Will use the training function traingdx and " stop ahead" a combination of methods to train BP network to improve the generalization ability of BP network)

MIMO 系统检测算法，最大似然（ML）,最小均方误差(MMSE),迫零(ZL),保证完美运行(MIMO system detection algorithm, maximum likelihood (ML), minimum mean square error (MMSE), zero forcing (ZL), to ensure perfect operation)

说明：  对布朗运动的方程求解 是个随机微分方程 进行求解(The solution of Brownian motion is a stochastic differential equation.)

蛇吃子的游戏，用matlab开发，非常好玩，有兴趣的同学可以看一下。(Snake game eat the child, with matlab development, very fun, interested students can look at.)

说明：  半导体数据训练集和测试集用来检测故障,使用MATLAB编程对数据采集(Semiconductor data training and test sets used to detect faults, using MATLAB programming for data collection)

图像滤波与傅里叶变化的matlaba源码(带注释)(Image filtering and Fourier transform of matlaba source code (with comments))

用matlab构建的信号发生器，其中包括交互界面，产生各种简单的波形，以及波形的混合叠加，以及外加音频的简单处理。交互界面中可以清楚看到波形的时域和频域的波形，包括波形的幅值，周期，功率均有图形显示(Constructed using matlab signal generator, including interface, simple treatment produces a variety of simple waveforms, and mixed superimposed waveforms, as well as external audio. Interactive interface, you can clearly see the waveform frequency domain and time domain waveforms, including the waveform amplitude, period, power has a graphic display )

一个m函数，可以读取GprMax2d的模型数据，是一个探底雷达正演模拟很有用的m代码(The m function model can the read GprMax2d the data, a dip radar forward simulation is useful m code)

简单ofdm调制代码，基于qpsk，有循环前缀，两种信道传输。(ofdm simulation based on qpsk.)
