【摘要】: 聚类是数据挖掘中常用的数据分析技术。本文详细介绍了FCM聚类算法的理论和实现步骤。并用Matlab 演
示了FCM用于数据聚类。结果表明FCM算法是一种高效的数据聚类算法, 有很广泛的应用。(FCM clustering analysis based on the data and Matlab implementation Ge Guohua, Xiao Haibo, Zhang Min (Institute of Information Engineering, Jiangxi University of Ganzhou, Jiangxi 341000, China) Abstract: Clustering is commonly used in data mining, data analysis techniques. This paper describes the FCM clustering algorithm theory and implementation steps. And demonstrates the use of Matlab for data clustering FCM. The results show that the FCM algorithm is an efficient data clustering algorithm, a very wide range of applications.)

实现9/7小波正反变换
注1： 采用标准正交方法，对行列采用不同矩阵（和matlab里不同）
注2： 为了保证正交，所有边界处理，全部采用循环处理
注3： 正交性验证，将单位阵带入函数，输出仍是单位阵（matlab不具有此性质）
注4： 此程序是矩阵实现，所以图像水平分量和垂直分量估计被交换位置
注5： 此程序实现的是类小波（wavelet-like）变换，是介于小波包变换与小波变换之间的变换
注6： 此程序每层变换相对原图像矩阵，产生的矩阵都是正交阵，这和小波包一致
注7： 但小波变换每层产生的矩阵，是相对每个待分解子块的正交矩阵，而不是原图像的正交矩阵
注8： 且小波变换产生的正交矩阵维数，随分解层数2分减少
注9: 提升系数可以在MATLAB7.0以上版本，用liftwave( 9.7 )获取，这里直接给出，考虑兼容性
注10：由于MATLAB数组下标从1开始，所以注意奇偶序列的变化
注11：d为对偶上升，即预测；p为原上升，即更新(Note 1: The standard orthogonal method, the ranks of the different matrices (and matlab where different)
Note 2: In order to ensure orthogonality, all boundary treatment, all with recycling
Note 3: Orthogonal validation, the identity matrix into the function, the output is still the unit matrix (matlab does not have this property)
Note 4: This program is a matrix to achieve, so the image horizontal and vertical components is estimated to be swapped
Note 5: This class implements the wavelet (wavelet-like) transformation, is between the wavelet packet transform and wavelet transform between
Note 6: This procedure transforms each image relative to the original matrix, the resulting matrix are orthogonal matrix, consistent with this and wavelet packet
Note 7: But each generation wavelet transform matrix, is to be broken down for each sub-block relative to the orthogonal matrix, rather than the original image of the orthogonal matrix
Note 8: Wavelet transf)

ZigBeeIEEE
The implementation was built on Matlab/Simulink using
fundamental components in Simulink to demonstrate how
reliably complex modulation schemes can be built, cost
effectively and efficiently [5]. The design of ZigBee
transmitter using MSK modulation is shown in the Figure 1.
Here we map input data bits to 8-chip PN sequences to be
transmitted and results in a chip rate of two mega chips per
second. After that, resultant chip sequence is send to the serial
to parallel converter. It is used here to separate the odd and
even bit indexed chips. Following this bipolar data formatting
is performed and signal modulated with a 2.4 GHz carrier on
the In Phase and QuadraturePhase data stream and adds it to
get the required transmitter output signal.
