Simple implementation of DFT/IDFT in matlab

验证可用，基于欧几里得距离的聚类分析，小波包分析提取振动信号中的特征频率。( Verification is available, Clustering analysis based on Euclidean distance, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  这个功能是用于Matlab中的某个功能所使用的，非常好的一个原代码！(This feature is used in a Matlab function used, very good a the original code!)

主成分分析pca算法matlab程序代码：pca标准化、协方差、特征根特征向量、方差贡献率。。。(Principal component analysis pca algorithm matlab code: pca standardized covariance, eigenvalues ​ ​ eigenvectors, the variance contribution rate. . .)

分别用矩形窗、汉宁窗、海明窗、三角窗和Blackman窗设计一 的线性相位带通滤波器，观察它们的3dB和20dB带宽，并比较五种窗的特点。(Respectively rectangular window, Hanning, Hamming window, triangular window and Blackman window design a linear phase bandpass filter, observe their 3dB and 20dB bandwidth and compare the characteristics of the five windows.)
