EIGENFREQ finds an approximation for the eigenfrequency of the resonator within a range and at a resolution specified by the user. The user specifies the range in terms of the minimum and maximum values of each of the real part and the imaginary part of frequency, and the user specifies the resolution in terms of the number of evenly-spaced real frequencies and complex frequencies at which EIGENFREQ is to performcalculations.

读取语音信号（用matlab的wavread指令），把语音信号分帧、加窗，进行清浊分割，提取基 频，这一部分较简单，自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数，可调用lpcfit.m 程序（我提供，见附件），将源、目标语音的浊音 段的lpc系数进行DTW规整，调用pathita2.m 程序（我提供，见附件）。将规整得到的lpc系数 转换成lsp参数，调用lpcar2ls.m 程序（我提供，见附件）， 再进行转换映射，调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)

计算啁啾，均匀，取样光栅透射谱。可以改变周期，占空比，长度等各种参数(Calculated chirp, evenly sampled grating transmission spectrum. Can change the various parameters of the period, duty cycle, length, etc.)

this is the code to do spectrum analysis using FFT.

小波包分析提取振动信号中的特征频率，有较好的参考价值，借鉴了主成分分析算法（PCA）。( Wavelet packet analysis to extract vibration signal characteristic frequency, There are good reference value, It draws on principal component analysis algorithm (PCA).)

蛇吃子的游戏，用matlab开发，非常好玩，有兴趣的同学可以看一下。(Snake game eat the child, with matlab development, very fun, interested students can look at.)

很全很详细的数学建模，关于参数估计问题的资料，有学习文档和Matlab源码，并附有练习题和相关数据，是学习参数估计的数学建模问题的很好的资料。(mathematical modeling，estimation of parameter，Matlab Praogram，pdf files)

本算法用来实现图像的首数字规则特性，首数字规则在1881年就被发现，他能检测图像的所有像素点的AC系数是否符合首数字规则(The first algorithm is used to achieve image characteristic figure rule, the first rule number 1881 was found that he can detect all the pixels in the image whether the First Digital AC coefficient rules)
