modified Gram-Schmidt (reduced QR factorization). A is a m-by-n matrix(m>=n)

the qpsk modulatio function

将线性模型拟合为线性或二次数据。 它是一个演示线性回归的脚本。 有益于学习(Fit a linear model to linear or quadratic data)

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.)

FILLNANS replaces all NaNs in array using inverse-distance weighting between non-NaN values.

对二维结构进行拓扑优化，基于变密度法的二维mbb梁的结构拓扑优化，迭代采用优化准则法，数值不稳定采用灵敏度过滤法。(Two-dimensional structure topology optimization, based on the variable density method of two-dimensional the MBB beam structure topology optimization, iterative optimization criteria, the numerical instability sensitivity filtration.)

matlabd的乱七八糟的没有用 不要下载(matlabd)

说明：  MATLAB预测程序(MATLAB forecasting process)

利用最大熵进行谱估计。本程序为matlab程序。(Using the maximum entropy spectrum estimation. This program is matlab program.)

prim算法的matlab，很好用~非常适合在图论中的应用~(the krusk algorithm matlab, very easy to use- very suitable for application in Graph Theory ~)
