Singulaar spectrum analysis code. (a version of PCA- principal component analysis)

Non-metric label propagation 的MATLAB 实现源码(the code of non-metric label propagation by matlab)

— In ultra-wideband (UWB) indoor dense multi-path transmission environments, traditional coherent Rake receiver requires estimation of channel parameters. Moreover, in order to collect enough signal energy from dense multi-path components, the number of Rake fingers must be large enough. Consequently, the receiver structure is too complex to be implemented in practice.

主要是用matlab实现的数字水印，其中用到的技术是lsb(Achieved using matlab digital watermarking, which uses the technology is LSB)

this is a matlab code with a gui that designs a shaft depending on the type of material needed the loads acting on it and the factor of safety

keep useful variables in the matlab workspace

介绍使用matlab的有限元分析的编程方法(introduce finite element programe using matlab)

用matlab编写的自适应遗传算法，交叉概率和变异概率能够自动随适应度而改变，因此能够提供相对某个最优解的最佳交叉概率和变异概率(Using matlab adaptive genetic algorithm, the crossover and mutation probability with the fitness change, and therefore able to provide relatively a optimal solution best crossover probability and mutation probability)

本函数将完成经典的w_svd模型下，数字水印的检测(This function will finish w_svd model, the classic digital watermark detection)
