Laplace_FDM_3D

Gauss Seidel equation solving for power system analysis

在matlab下仿真计算光纤的色散和自相位调制特性(Simulation of fiber dispersion and self-phase modulation characteristics)

说明：  这是用MATLAB仿真平台，实现无线传感器网络定位算法仿真。(This is a MATLAB simulation platform, wireless sensor network localization algorithm simulation.)

FFT Filters provide precisely controlled low- and high-pass filtering (smoothing and sharpening, respectively) using a Butterworth characteristic. The image is converted into spatial frequencies using a Fast Fourier Transform, the appropriate filter is applied, and the image is converted back using an inverse FFT

Kalman滤波理论详细介绍，包括卡尔曼的各种扩展滤波方法都有详细的说明，适合初学者普及知识与相关知识框架的架构。同时还介绍了其在飞机导航中的应用(Kalman filtering theory in detail, including the extended Kalman filtering methods have a variety of detailed instructions for beginners popularize knowledge and knowledge framework architecture. It also presents its application in aircraft navigation)

采用基本三角、方波信号等，对ECG心电信号仿真(Using the basic triangle, square wave signals, for ECG ECG simulation)

该程序是方向滤波器工具包，其中有很多现成的滤波器，及上下采样程序。可直接调用。(The program is the direction filter kit, there are many ready-made filter, and down sampling procedure. Can be called directly.)

这是一个Z变换和Z反变换的matlab程序。(This is an anti-Z transform and Z transform matlab procedures.)

说明：  Cachy分布，产生cachy 分布的概率密度，随机数(Cachy distribution)
