k-means 算法接受输入量 k ；然后将n个数据对象划分为 k个聚类以便使得所获得的聚类满足：同一聚类中的对象相似度较高；而不同聚类中的对象相似度较小。聚类相似度是利用各聚类中对象的均值所获得一个“中心对象”（引力中心）来进行计算的。(k-means algorithm accepts input k then n data objects into k clusters in order to make clustering satisfy obtained: the objects in the same cluster high similarity different clustering object similarity small. Cluster similarity is the use of the mean of each cluster of objects that get a " central object" (center of gravity) to perform the calculation.)

This file designs two stage Nyquist filters with a given rolloff and desired ripples of Dc and Ds. The design aims to find the lowet number of multipliers. The main file is called Design_Double.m The matlab script is based on the design method in the following article: A. Eghbali, T. Saramä ki, and H. Johansson, "On two-stage Nyquist pulse shaping filters," IEEE Trans. Signal Processing, vol. 60, no. 1, pp. 483-488, Jan. 2012. Please cite the above article if you use this file. In case o
