Implementation of FxLMS algorithm for a single channel feed-forward active noise control system.

AP聚类方法，是08年发表在“科学”上的聚类方法，本人从图像图像方面研究近十年，这是我所见过最好的聚类算法，本程序提供聚类演示，还把它用图像分割试验（matlab7.0环境调试）。(AP clustering method, is 08 published in " Science" on the clustering method, the image from the image in my research in recent years, this is the best I have ever seen clustering algorithm, Clustering presentation of this program provides, but also test it with the image segmentation (matlab7.0 debugging environment).)

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.
