基于matlab的对运动目标的检测程序，可以实现固定背景下运动目标的检测(Matlab-based moving targets on the testing procedures, can be fixed against the background of the detection of moving targets)

cognitive Radio simulation in matlab thanks

采用卡尔曼滤波的方式对时间进行预测，有较好预测精度(Kalman filter is used to predict the way time high prediction accuracy)

This is a matlab code for geostatictics

timing_recovery:The importance of the work is reflected in supporting the development of new technologies and their adaptation to existing infrastructures. From the economic point of view, the final product is more efficient, flexible it can be widely available and less expensive than existing similar products

上海交大硕士毕业论文《基于最小熵谱估计的 高频重建算法研究》：本论文提出了一种基于最小熵谱估计的高频重建算法（论文中简称为（MEHFR），该算法利用最小熵准则对信号谱进行外推，从而重建出音频信号的高频分量，论文同时对提出的MEHFR算法作了改进和性能分析，并给出了MEHFR成功应用于目前主流音频编解码器——MP3的一个实例(This thesis puts forward an algorithm of high frequency reconstruction based on minimum entropy spectral estimation (called MEHFR in this thesis). MEHFR spreads the spectrum in the principle of minimum entropy and reconstructs the high frequency of audio signals also this thesis improves MEHFR and shows the analyses of performance at last applies MEHFR to ME3 which is the most popular codec of audio.)

计算复合材料的基本物理性能参数,包括弹性模量，泊松比，密度，热导率，热膨胀系数(Calculation of the basic physical parameters of composite materials )

用分布傅里叶计算硅波导中的非线性薛定谔方程，考虑硅波导中色散及非线性损耗(solution of NLSE(two pulses propagate in silicon waveguide) using split step fourier method)

说明：  实现神经网络的bp识别手写数字。改程序师用MATLAB实现的，里面代码可以直接用(Bp neural network to achieve handwritten numeral recognition. Reform program to achieve the division to use MATLAB, which code can be directly used)
