说明：  matlab 实现dbscan 这是一种基于密度的聚类分析算法，可以发现任意形状的簇，可以发现噪声点。(Realization of DBSCAN with MATLAB This is a density based clustering analysis algorithm, which can find clusters of arbitrary shape and noise points.)

finding a root by position of falses

一个有趣的matlab编程的俄罗斯方块。编程思想值得一学！J向左，L向右，I变换，S向下。(An interesting matlab programming Tetris. Programming ideas worth learning! J to the left, L to the right, I transform, S down.)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )
