matlab 函数大全，编写matlab程序时供参考(matlab functions, for reference when writing matlab program)

关于matlab的一些知识，希望对大家有所帮助。(Some knowledge about matlab, we want to help.)

小波包分析提取振动信号中的特征频率，是小学期课程设计的题目，采用的是通用的平面波展开法。( Wavelet packet analysis to extract vibration signal characteristic frequency, Is the topic of the elementary school stage curriculum design, Using common plane wave expansion method.)

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.)

能够实现MATLAB中quad积分函数的功能，文件中举了一个简单的例子(MATLAB quad integral function of the function can be achieved, cited a simple example file)

在matlab环境下，利用ofdm实现的uwb。(In the matlab environment, the use of ofdm implementation uwb.)

说明：  该程序在MATLAB环境下编译，用于重构一维时间序列的相空间轨迹，并找出最佳的重构延迟步长或时间。(The program compiled in MATLAB environment for the reconstruction of time series of one-dimensional phase space trajectory, and the Reconstruction of the best step length or time delay.)

模糊T-S预测控制的matlab代码，实现基于模糊模型辨识的广义预测控制(TS fuzzy matlab code predictive control, fuzzy model identification-based generalized predictive control)
