这是一个利用matlab编写的从Earth center earth fix 坐标转到east north up 坐标系的一个matlab代码(This is a Matlab prepared from the center of Earth, earth fix the coordinates to the east north up the coordinate system of a matlab code)

folyd算法的matlab，很好用~非常适合在图论中的应用~(folyd algorithm matlab, with very good ~ very suitable for application in Graph Theory ~)

地震信号处理，虚同相轴方法预测层间多次波，将数据分成上下两部分，利用相关和褶积的原理预测出层间多次波。预测信号和原始信号在相位和振幅上存在差异，用L1范数匹配法进行匹配，其中，提供了两种方法解病态方程，分别为高斯-赛德尔方法和正则化方法。(Seismic signal processing, predicte internal multiples by construct virtual events .The data is divided into two parts, using the principle of correlation and convolution to predicte multiples. There are differences between the prediction signal and the original signal on the phase and amplitude, so we use the L1 norm method to match the singal.We provide two methods for solving ill equation, respectively Gauss- Seidel method and regularization method.)

基于FFT的频谱分析程序，包含感应电机定子电流数据，可直接运行(FFT based spectrum analysis program, including the induction motor stator current data, can be directly run)
