说明：  matalb的原代码主要用圆管的分析，应该有实用价值。(Dimensional analysis and scaling ：Dimensional analysis is a tool based on the observations )

在matlab开发环境下实现了模拟退火的智能算法程序(In the matlab development environment can only achieve a simulated annealing algorithm)

点源定通量地下水污染物非稳定迁移计算程序,程序内有中文说明。(point source pollutants given steady migration flux calculation procedures)

此程序是有关于到达角DOA估计的代码，在很多方面都很有用(This procedure is DOA on arrival estimation code, very useful in many ways)

采用64QAM调制信号的OFDM信号的生成(OFDM with 64QAM modulation signal generated signal)

In any power system, stability is always a important parameter. To check the stability of a synchronous generator which is connected with the grid is the power angle and freq need to know. With the help of this simulation model one can easily find Power angle and Freq.

说明：  学习matlab的分享，欢迎下载，共享，学习。(language of matlab important)

ecg signals for the analysis

function Px=overlay(N,omega,A,sigma,num) OVERLAY Forms multiple power spectral density estimates. ------- USAGE Px=overlay(N,omega,A,sigma,num) Calculates the periodogram using an ensemble of realizations of a process consisting of a sum of complex exponential in white noise. N : length of the signal omega : vector containing the sinusoid frequencies A : vector containing the sinusoid frequencies sigma : the variance of the white noise num : size of the ensemble (number of periodograms)
