说明：  傅里叶变换我们都知道，那怎么来实现快速傅里叶变换呢？(Fourier transform we all know, how to achieve the fast Fourier transform it?)

说明：  可以实现有理数倍采样率转换，并有输入输出结果分析，比较(multirate)

提出利用电云进行模型重构的算法，该算法基于点云的几何形状特征，很好的算法。(Proposed the use of electric cloud model reconstruction algorithm based on the geometric shape of the point cloud, a good algorithm.)

利用matlab自带的一些程序，编写的一些滤波程序。包括线性平滑滤波、中值滤波、状态统计滤波等。(Matlab comes with some procedures, the preparation of some of the filtering process. Including linear smoothing filter, median filter, the state statistical filtering.)

已知一个序列x(n)=0.5cos(0.55*pi*n)+cos(0.45*pi*n),时域FFT分析其频谱。 （1）使用不同宽度的矩形窗截断该序列为M点，取M分别为：20，40，160,观察不同长度对频谱影响；（2）使用哈明窗和凯泽窗重做；（3）对三种窗的结果进行分析比较；（4）总结窗类型和长度对频谱分析的影响。 (Known a sequence x (n) = 0.5cos (0.55* pi* n)+ Cos (0.45* pi* n), time-domain FFT analysis of its spectrum. (1) use a different width of the rectangular window of the sequence for M cut-off point, take M are as follows: 20,40,160, observing the impact of different lengths of the spectrum (2) the use of Hamming window and the Kaiser window redo (3 ) on the three windows analyzed and compared the results (4) summarize the type and length of window for spectrum analysis.)

别人编写插值与拟合的程序，拿回来一直没有用到，不知道对诸位有没有用(Others prepare interpolation and fitting procedures used have not been back, I do not know of you have no use)
