实现FFT频谱分析，IIR数字滤波器的设计（多种方法），FIR数字滤波器的设计(Implement FFT spectrum analysis, IIR digital filter design (many ways), FIR digital filter design)

This program return the average centrality for a graph for different value of x.

MATLAB函数大全，常用函数全部覆盖。(Encyclopedia of MATLAB functions, covering all commonly used functions.)

这是较好的Matlab源代码，希望此代码能对大家有所帮助。(This is a better Matlab source code, I hope this code can be helpful to everyone.)

自己编写的迭带的阈值设定的方法.可以直接调用..这种阈值方法比较适合背景与前景差别比较大的情况. (I have written again and again with the threshold settings. .. This can directly call methods suitable threshold background and the prospect of relatively large differences.)

我用的实现图像分水岭分割的代码！感觉还可以，要用的自己拿去改改(I use the watershed segmentation of image code!)

说明：  瑞利随机数的生成，通过两个同方差的正态分布而求得，并求出其PDF和CDF(Rayleigh random numbers generated by two normal distribution with variance that obtained and solved its PDF and CDF)

说明：  信道模型为带多普勒频移的瑞利衰落信道，关于线性插值的MATLAB仿真程序，并解调。(Channel model with Doppler frequency shift for the Rayleigh fading channel, on the linear interpolation of the MATLAB simulation procedures, and demodulator.)

后向欧拉方法求解微分方程的初值问题，运用牛顿迭代解决implicit(backward euler solver for ODE)

说明：  交叉口matlab实现，本程序可以较好的实现交叉口的模拟，请放心使用(Intersection matlab implementation, the program can achieve a better simulation of the intersection, please be assured use)
