Main.m为粒子群算法程序,属于优化类，data.txt为粒子群算法的数据文件(The Main.m particle swarm optimization procedures, belonging to the optimization class data file data.txt for the particle swarm algorithm)

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)
