带有matlab源程序 实现了dtmf，添加了GUI界面(matlab gui)

施瓦茨变换，用于半无穷大平面的变换，matlab代码(Schwartz transform for the conversion of semi-infinite plane, matlab code)

该代码实现了“大津法”，也就是最大类间方差算法，完全由本人自己编写，结果很好。(The code of the " Otsu method" , which is the Otsu algorithm, written entirely by my own, good results.)

数学建模中常用算法，应用十分广泛。此为此算法的Matlab程序，希望有用。(Commonly used mathematical modeling algorithm is widely used. The Matlab program for this algorithm, hope helpful.)

粒子滤波 PF( Particle Filtering) 是在 贝叶斯滤波框架下基于 Monte Carlo 采样的统计滤波方法，可解 决非线性、非高斯的滤波问题，声源跟踪就属于这类问题。近年 来，基于粒子滤波的声源跟踪算法已成为研究的热点。 (he real acoustic data recorded in a typi- cal meeting room using a small-scale microphone array is used for tracking experiments． Results show that the proposed algorithm can realise effectively the orientation tracking of the randomly walking speaker，in which，the root mean square error of tracking in direction of the hori- zontal angle and the elevation are all less than 5°． )
