matlab工具函数 DIR2PAR 函数(Matlab tool function DIR2PAR function)

Matlab codes for descriptors

这个程序是幅值谱中校正频谱峰值的比值校正法，可以自设定校正谱峰值的个数，比值校正法还可以校正相位，校正的结果很准确(This procedure is correction of the amplitude spectrum of the ratio of the peak spectrum correction method, correction can be set from the number of spectral peaks, the ratio correction method can also be correction phase, the results of very accurate correction)

matlab编码程序 主成分分析 有实例 直接应用即可(Matlab coding program principal component analysis is directly applied to an example.)

说明：  MATLAB的学习，以及仿真B超的field II 软件以及使用说明书(MATLAB )

介绍线性预测编码(LPC)及其基本原理，由语音信号常用的全极点模型的传递函数推导出线性预测方程，(Introduction of linear predictive coding (LPC) and the basic principles of commonly used by the speech signal transfer function of all-pole model of a linear prediction equation is derived,)

WAP to generate a random noise of amplitude

ACF(x) plots the sample autocorrelation function of the univariate time series in vector x. By default, the sample autocorrelation function is plotted up to lag 25. ACF(x,k) plots the sample autocorrelation function up to lag k. ACF(X,k, name ) sets the title of the plot to name .
