直接扩频系统常用函数，有助于对直接扩频系统的算法研究。(functions for Direct spread spectrum system,guod referense for the study for Direct spread spectrum system)

计算近似熵、改进的样本熵及优化的模糊熵,均为matlab下编辑的程序，是很好的复杂度指标(approxy entropy, sample entropy and fuzzy entropy matlab code )

ABAQUS/Standard 用户材料子程序实例(A standard ABAQUS UMAT workexample.)

ECONOMIC LOAD DISPATCH WITH NUMBER OF GENERATORS WITH PRODUCTION LEVEL AT DIFFERENT INTERVALS OF TIME.

说明：  改写的matlab fft程序，能对fft结果幅度调整和对横坐标的频率实行自动匹配(Matlab fft procedure adapted to the results of the fft and the abscissa is adjusted automatically to match the frequency of)

一份学习Matlab混合编程的资料，很值得初学者看一下(Study mix program of MATLAB)

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )
