关于地震信号处理的径向道的应用 (Seismic signal processing on the application of radial Road)

dijkstra算法的matlab实现，最短路问题的一种解法。(dijkstra algorithm Matlab implementation, the shortest path to a solution of the problem.)

这是一个LZW解压的matlab子函数程序和主函数，要结合我第一个上传的LZW压缩来看，这样有助于理解，效果很少明显，压缩率80 以上，不懂的跟我联系，我交你！！！我弄懂了！(It is a realisation of lzw decompression.Its compression ratio is beyond 80 .Its compression source is the first file which I have uploaded.If you have some questions,you can contact with me.)

LS-DYNA动力学分析，主要适用于显式动力学分析，本程序主要是K文件，希望能给大家了解一点如何修改K文件。(LS-DYNA dynamics analysis, mainly applied in the explicit dynamics analysis, this procedure is mainly K file, I hope everyone can understand a little how to modify the K file.)

说明：  为Matlab的日历显示加上农历信息。 (There is a command named "calendar" in MATLAB for get calendar infomation. This code improve the calendar information with the lunar.)

可以计算双包层光纤耦合系数，采用耦合模方程计算(Can be calculated double cladding fiber coupling coefficient)

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)
