求星图中星象坐标的matlab函数，输入星图，利用交叉投影方法得到星象所在区域的四个顶点坐标和星象的质心，能够快速的求得星图星象的位置信息(Astrology chart for stars matlab function of the coordinates, enter the star maps, cross-projection method using astrology region and the four vertex coordinates of the mass center of astrology, the Express can find the location of star maps astrology information)

说明：  一维的基于时域有限查分方法的MATLAB程序，初学者学习FDTD用(One-dimensional time-domain finite-based methods of investigation points MATLAB program for beginners to learn to use FDTD)

主要是应用pso工具箱来优化函数griewank，实现粒子群对函数的测试(Mainly applications pso toolbox to optimize function griewank, and particle swarm function test)

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. (This is a model of a QPSK modulation system f or transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC)

说明：  主成分分析法，用于将低数据维度，减小有相关性的数据特征。(dimensionality reduction)

超宽带脉冲幅度调制接收端频谱，与其他的几个共用(Ultra-wideband pulse amplitude modulation spectrum receiver, and some other common)

该段程序实现的是模糊PID控制。讲模糊控制技术和PID控制结合起来，不仅满足线性系统的需求，更适合于非线性系统。(This section of the program to achieve fuzzy PID control. Stresses combine fuzzy control and PID control, not only meet the demand of the linear system, more suitable for non-linear systems.)
