PID-Control

本人收集matlab实现最小二乘法线性、一元多项式拟合、多元二次拟合、自编函数曲线拟合程序，有文档说明(I collect the linear least squares method matlab realize, one yuan polynomial fitting, multivariate quadratic fit, self-function curve fitting procedures, documentation)

绘制单颗卫星、单架飞机的时延多普勒图形。(Plot DelayDoppler of single target.)

This was used at the 2004 Cyber Summer Camp This program hides a message image in the lower bit planes of a cover image

两靖rayleigh衰落信道仿真。This m-file uses successive iterations of data to create an animated = effect ％showing the results of passing an unmodulated carrier through a simple = two ％path Rayleigh fading channel. The following formula and diagram ％illustrates the m-file operation. The animation shows, input(blue) ％and the output(red), the the phase shifts, gains, and attenuations ％of the output sine wave or carrier.(Two Jing Rayleigh fading channel simulation.
