IIR滤波器设计
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).)

RepeatFCM
FCM算法是一种基于划分的聚类算法,它的思想就是使得被划分到同一簇的对象之间相似度最大,而不同簇之间的相似度最小。模糊C均值算法是普通C均值算法的改进,普通C均值算法对于数据的划分是硬性的,而FCM则是一种柔性的模糊划分(FCM algorithm is a clustering algorithm based on the division, which makes the idea is to be divided into clusters with the greatest similarity between the object, and the similarity between different cluster minimum. Fuzzy C-means algorithm is an ordinary C-means algorithm, the general C-means algorithm for the data are divided into hard and fast, and FCM is a soft fuzzy partition)

:元胞自动机不仅是理论计算机科学领域的一个重要的计算模型,而且可视为一无限维的离散动力系统,被广泛应用于
自然科学和社会科学各领域的复杂性的研究中,是一个重要的研究方法和工具。该文以Matlab 为开发工具,开发了元胞自
动机的可视模型,为其在各个领域的复杂性研究提供了一个简易、可行的计算机仿真工具(MATLAB s version of Conway s Game of Life.
"Life" is a cellular automaton invented by John
Conway that involves live and dead cells in a
rectangular, two-dimensional universe. In MATLAB, the universe is a sparse matrix that is initially all zero.
Whether cells stay alive, die, or nerate new cells depends upon how many of their eight
possible neighbors are alive. By using sparse matrices, the calculations required become astonishingly simple. We use periodic (torus) boundary conditions at the edges of the
universe. Pressing the "Start" button
automatically seeds this universe with several small random communities. Some will succeed and some will fail. )
