无多普勒频移的海底混响单元散射模型卷积法-matlab(the seafloor reverberation unit scattering model convolution method without Doppler frequency shift )

一个GPS课程的全部代码，含有数据！很实用(MATLAB GPS SCRIPTS-- Charles Meertens and Doug Miller, U. Utah 3Jan95 These scripts were developed for/during a class in GPS and Active Tectonics Department of Geology and Geophysics, U. Utah, Spring, 1994 EXAMPLE RINEX Files (the only ones guaranteed to work this release) CUR10911.94N CUR10911.94O PAR10910.94N PAR10910.94O Main Program scripts: gpshora.m -- function to calculate Modified Julian Day, Homework#1 HW2.m -- Homework#2 read RINEX observation file and plot C/A code vrs. time HW3_plt.m-- Homework#3 read RINEX navigation file, plot satellite positions HW3_3dplt.m-- Same as HW3_plt.m, but 3d position plots HW4.m-- Homework#4 calculate and plot station position as function of time Functions called: calc_nav.m-- calculate satellite position calc_pos1.m-- calculate station position constants.m-- GPS constants coords.m-- convert x,y,z coordinates to lat, long, height date2j.m-- calculate MDJ eccenr.m-- calculate "E" anomally read_nav.m-- Read RINEX Nav file r)

说明：  这是一个LS-SVM的预测实例，主要实现对击穿电压的预测出图形，希望能够给与帮助~(This is an instance of LS-SVM' s prediction, the main achievement of the predicted breakdown voltage graph, hoping to give help ~)

用计算机语言编写图的连通性判断算法，可输入图的邻接矩阵，判断图是否连通以及确定连通分支的个数，掌握Warshell算法或矩阵幂算法的实现方法。(Written in a computer language to determine the connectivity graph algorithms, you can enter the adjacency matrix to determine whether the connectivity map and determining the number of branch connectivity, master implementation Warshell algorithm or matrix power algorithm.)

说明：  异步电机矢量控制程序，通过调节转矩，电机可以具有快速动态响应(By adjusting the torque, the motor can have fast dynamic response)

shielding effectiveness of the materials

半阈值法小波去噪，并与硬阈值和软阈值的结果进行比较(Semi-threshold wavelet denoising, and with the hard threshold and soft threshold to compare the results of)

说明：  zero sequence caliculation

利用MAtlab消除噪声，尝试高低通滤波(use MAtlab eliminate noise, high or low pass filtering to)

生成一个正弦信号，并加入白噪声，得到正弦信号以及白噪声的混合信号，通过低通滤波器对白噪声进行处理(generate a sinusoidal signal, and add white noise, sinusoidal signal to be white noise and mixed-signal, through low-pass filter white noise processing)
