模拟退火算法的解决 具体在mATlab实现算法 (matlab)

Used to obtain the particular position where a maximum or minimum occurs in a matrix

说明：  多目标遗传算法二代，可直接使用，内有详细说明(NSGA_2,can be used directly,which is explained in detail)

一个用来计算一种钻石形三维的光子晶体的能带结构的程序(A diamond is used to calculate a three-dimensional photonic crystals with the structure of the program)

衰落信道仿真 function r = rayleigh( fd, fs, Ns ) r = rayleigh(fd,fs,N) A Rayleigh fading simulator based on Clarke s Model Creates a Rayleigh random process with PSD determined by the vehicle s speed. INPUTS: fd = doppler frequency set fd = v*cos(theta)/lambda v = velocity (meters per second) lambda = carrier wavelength (meters) theta = angle w/ respect to tangent (radians). fs = sample frequency (Samples per second) Ns = number of samples of the Rayleigh fading process to produce OUTPUTS: r = row vector containing Ns samples of the Rayleigh fading process Author: Matthew C. Valenti Mobile and Portable Radio Research Group Virginia Tech For Academic Use Only (Fading channel simulation)
