gives the initial and final velocities of a trajectory connecting R0 to Rf over a transfer time of dT. This method uses universal variables, from Vallado.

two link pendulum matlab simulation

自行编程，采用有限差分法，求解画出微带线电场线分布图。注释详细(Own programming, using the finite difference method, seeking microstrip line power line distribution.)

基于matlab的条件平差，实现测绘计算工作的简化(Adjustment based on the conditions of matlab)

用于网络服务的matlab源程序，没有解压密码，可直接打开使用(network services for the Matlab source, without extracting passwords, can be directly used to open)

局部均值分解(Local Mean Decomposition)，处理非线性非平稳信号的一个方法，LMD是依据信号本身的信息进行自适应分解(Local Mean Decomposition, a method for processing nonlinear non-stationary signals, LMD is adaptive decomposition based on the information of the signal itself.)

一个剪切波变化工具箱，里边程序很全，有范例，值得拥有(A shear wave change toolbox, inside the program is full, there are examples worth having)

矢量控制系统中的PARK变换，CLARKE变换以及他们的反变换(PARK transformation vector control system, CLARKE transform and inverse transform)

本段程序主要是运用小波去噪对信号进行处理(This segment is mainly the use of wavelet de-noising procedure for signal processing)

说明：  噪声调频信号的产生：1、产生高斯噪声电压 2。用6极点椭圆滤波器形成噪声带宽 3。将滤波器输出送到一压控震荡器，输出即为调频噪声干扰信号(Noise FM signal generation: 1, resulting in Gaussian noise voltages 2. 6-pole elliptic filter noise bandwidth of the formation of 3. The filter output to a voltage controlled oscillator output signal noise shall be FM)
