平均幅度差函数法基音周期的提取 包含滤波、中值平滑等处理。(Average magnitude difference function pitch extraction method includes filtering, median smoothing, such as treatment.)

关于matlab的中文帮助，对于一些初学的且英语不好的同学有用(on Matlab Chinese help for the novice and some bad English students useful)

聚类算法工具包，包含31个m文件。参考文献是 《Impact of Similarity Measures on Web-page Clustering》。(The clustering algorithm Kit 31 m file. References " Impact of Similarity Measures on Web-page Clustering" )

随机游走类似布朗运动，就是随机的向各个方向走吧。 虽然代码没什么技术含量，不过产生的图像实在太漂亮了，所以还是贴上来吧。 产生的图像：(Similar to Brownian motion random walk, is random and go in all directions. Although the code is no technical content, but the resulting image is too beautiful, so it is still Tieshanglai it. graphics layer.)
