The median filtering algorithm on matlab

现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的： 低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4) 高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3) 带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4) 带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3) 1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。 (an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)

By the harmonic elimination technique,we can solve for the switching angles of a half bridge to cancel the 5th, 7th, 11th and 13th harmonics by the Newton Raphson iteration technique.

matlab函数，指令集。包括语法和描述(matlab function and instruction set. Including syntax and description)

说明：  

matlab实现链表的操作,希望对大家有所帮助(matlab realize the operation of the list, we want to help)

Panel Code in MATLAB Coded by L. sankar, April 1997

说明：  用Floyd算法设计的最小费用最大流，求最大流时，用的是标号算法(Floyd algorithm design with the minimum cost maximum flow, for maximum flow, the algorithm is labeling)

unifpdf是一种计算均匀分布概率密度的函数，在生成随机数算法中有重要应用。(unifpdf is a calculation of the probability density function of a uniform distribution, have important applications in random number generation algorithm.)
