Potential-flow

对一个系统进行超前或滞后矫正的matlab程序 希望对大家有用(Lead or lag correction)

距离保护R-L模型算法 使用图基滤波器 控制阻抗轨迹显示范围 在阻抗平面画出阻抗圆特性、整定阻抗直线特性和短路阻抗轨迹( RL model algorithm for distance protection using map-based filter control the impedance locus in the impedance plane display range characteristic impedance circle draw, setting characteristics and short-circuit impedance line impedance locus)

二次多项式拟合大地水准面，采用matlab编写的，关于拟合出来的图像感觉有些问题。。希望大家指正(Quadratic polynomial fitting geoid, using matlab prepared some questions about the fitting out of the picture feel. . I hope you correct)

matlab的准线性集合，可以求出线性参数及误差，并且可以得到极值(matlab quasi-linear collection of linear parameters and error can be calculated, and you can get the extreme value)

本程序是一个直接扩频序列仿真包，直接序列扩频的mdl文件，未设参数(This procedure is a direct sequence spread spectrum packet simulation. Need matlab installed can only be used simulink.)

load flow for ds having main line only

EKF求解GPS粗码。实时性高，精度高。主要为导航定位设计(EKF crude for GPS code. Real-time high and high accuracy. Mainly for navigation design)

for edge detection(linear detection as road) in radar images we can use the morphology technique. here i am coding fo morphology process to detect the linear feature of an image.
