说明：  非常适合参加数学建模大赛的资料，希望与大家共享！(Suited to participate in mathematical modeling contest information, and we wish to share!)

代码较长但是很清楚的将伪码-线性调频信号和线性调频信号以及GOLD序列信号的频谱图表示出来并最后得出伪码线性调频信号的模糊函数图(Code is longer but it is clear that the pseudo-code- spectrum chirp chirp signals and signals as well as signals GOLD sequence and came to the conclusion that out pseudo-code chirp signal ambiguity function diagram)

经典SVM算法matlab程序,用于多种利用MATLAB对数据进行SVM仿真的实验。(Classical SVM algorithm matlab program for a variety of SVM data using MATLAB simulation experiments.)

说明：  通过不同大小的窗口移动，计算每个窗口内地形剖面数据的均方根值，得到的数据在双对数图中拟合直线可求得分维数(move the windows of different size and calculate the rms of the data in the window.Then using the resultant data to plot,so that the fractal dimension can be gotten.)

用于有色噪声的卡尔曼滤波，是无迹卡尔曼滤波(For colored noise Kalman filter, unscented Kalman filter)

利用MATLAB的反馈网络-Elman神经网络处理时间序列问题的功能预测上证股市开盘价。(Elman Feedback network using MATLAB neural network for time series prediction problem function on card stock market opening.)

不同光程比值对色散关系的影响，光子晶体中光程的比值定义为高低折射率所对应的光程的比值，计算公式为定义为 (Effects of different length ratio on the dispersion relation)

说明：  此程序基于VV算法的载波相位估计。该算法既可以估计载波初始相位差。这种算法估计的精确度高。(This program is based on the carrier phase estimation of VV algorithm. The algorithm can estimate the initial carrier phase difference. The accuracy of this algorithm is high.)

Matlab 6.X辅助小波分析与应用的源码，有许多matlab小波的代码(Matlab 6.X auxiliary source and application of wavelet analysis, there are many wavelet matlab code)

两个频率的凹口滤波的干扰对消噪声，采用了SER算法，可以和LMS算法来做比较。(Filtering the interference of the two frequencies of the recess on the noise-cancellation of the SER algorithm, and the LMS algorithm for comparison.)
