pso优化lssm的matlab程序，用于文件文本等的分类或者研究工作(Pso- LSSM matlab used in file, such as classification or research work)

数值微分精度及步长的关系，截断误差和舍入误差，体会误差对结果的影响，用算法1 和算法2 分别得到的结果进行比较，由Taylor公式可得到两种算法的截断误差(Accuracy of numerical differentiation and the relationship between step length, truncation error and rounding error, the error on the results of experience with algorithm 1 and algorithm 2 respectively, to compare the results obtained by the Taylor formula for the truncation error of two algorithms available)

这是认知无线电检测中的循环检测代码，希望大家享用(This is the cognitive radio detection loop detection code, I hope you enjoy)

implement the Power Al- gorithm for the computation of themaximumeigenvalue of Aj . Write a function Power_Algorithm which takes as input A q (the initial approximation of the eigenvector) and scale (it was given as  in the lectures).

some examples to learn basic c++

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. )
