We will consider trajectories that lie in a plane passing through the center of the planet, so that we permit no out-of-plane forces in the following analyses. The general nature of the trajectory and the variables describing it are shown in Figure 3-1 below

说明：  利用三次样条函数计算土样Cu／Cc，有matlab代码(Use of cubic spline function calculated soil samples Cu/Cc, there is matlab code)

Carrier Recovery Using a Second Order Costas Loop

This method handles the border by repeating the closest values to the point accessed. This is different from matlabs border handling.

本文档是MATLAB详细的教程课件，对MATLAB初学者来说是很好的一部教材。对大家肯定会有很大的帮助的。(This document is a detailed tutorial MATLAB software for beginners MATLAB is a very good teaching. I am sure you will be on a lot of help.)

关于信号处理方面音效移频中解析信号的产生方法，该方法让人耳目一新，通过先设计频域，再求逆，时域上进行采样，得到两个FIR滤波器逼近希尔伯特变换器。(Aboat an efficient method of analytical signal generation in audio frequency shift.This method refreshing, first design in the frequency domain, then sampling in the time domain, getting two FIR filters approximate Hilbert transform.)

相控阵技术广泛应用于雷达、导航、声呐等领域，该文件为matlab及HFSS对相控阵的仿真，很经典(Phased array technology is widely used in radar, navigation, sonar and other fields, the file is matlab and HFSS simulation for phased array, classic)

曲线的卡尔曼滤波程序仅供参考。谢谢大家的支持。要是好的话多支持我啊(good)

做的关于弹性波的数值模拟应用的PML边界对于初步研究地震波传播理论的人有很好的指导意义(sdfgweryytgw4e6tuwsdfg)
