Noise Estimation of speech signals in Matlab

模式识别线性判别的程序实现，产生两个二维正态分布随机样本，分别进行Fisher线性分类和感知器分类。其中main.m是主函数，将三个程序放在同一文件夹中，运行main.m即可得到分类结果。(Pattern recognition linear discriminant program implementation, generate two-dimensional normal random sample, were Fisher linear classifier and Perceptron classification. Main.m is the main function of which will be three programs in the same folder, run main.m classification results can be obtained.)

粒子群算法源程序，是近年来发展起来的一种新的进化算法。有实现容易、精度高、收敛快等优点。是一种并行算法。(Particle swarm algorithm source code, is a new evolutionary algorithm developed in recent years. There are easy to implement, high precision, fast convergence and so on. Is a kind of parallel algorithms.)

利用MATLAB的声音频谱信号的采集、分析和处理，最后形成报表处理(Analysis and processing of the sound spectrum signal acquisition by MATLAB, and finally the formation of report processing)

eng_mat.rar是matlab实例,有的matlab安装时不带，可以下载拷到matlab的example文件夹里(eng_mat.rar is the matlab example, matlab installed some without, you can download the example Kaodao matlab folder)
