说明：  粒子群算法解决VRP代码（matlab）(Particle swarm algorithm to solve VRP code (matlab))

通过matlab实现Nyquist滤波器(realization of Nyquist filter)

this code gives minimum peak to average power ratio. the technique used here is adding peak reduction carriers

FEM method in 2D problem

image processing-average

说明：  迭代法 迭代式阈值选取的基本思路是:首先根据图像中物体的灰度分布情况， 选取一个近似阈值作为初始阈值(Iterative threshold selected basic idea is: First, the gray-scale distribution of objects in the image, select an approximate threshold as initial threshold)

Fit time series Q(t) to a logistic function. Inputs (vectors of same size): t (time) & Q Outputs: Qpre (logistic model fit to data) and three independent parameters: thalf, Qinf, and a, describing the logistic Q(t) = Qinf/(1 + exp(-a*(t-thalf))) Qinf is value as t --> infinity thalf is time of symmetric inflection point a is time decay constant Written by James Conder, Southern Illinois University, Oct. 2010
