【问题标题】:Hexagonal grid representing a cellular network as used in mobile communication systems表示移动通信系统中使用的蜂窝网络的六边形网格
【发布时间】:2015-03-13 20:07:43
【问题描述】:
我对 Matlab 比较陌生,我想生成一个六边形网格来表示蜂窝网络,其中每个六边形都有特定的行为。
我的问题是如何从方形网格变为六角网格(传输矩阵)?这是我目前所拥有的。
[X,Y] = meshgrid(0:60);
figure(1), plot(X,Y,'b')
hold on, plot(Y,X,'b')
axis square

【解决方案1】:
几年前,我为此编写了一些代码:
%// Define input data:
close all
clear all
M_max = 14; %// number of cells in vertical direction
N_max = 10; %// number of cells in horizontal direction
trans = 1; %// hexagon orientation (0 or 1)
%// Do the plotting:
hold on
for m = -M_max:M_max
for n = -N_max:N_max
center = [.5 sqrt(3)/2] + m*[0 -sqrt(3)] + n*[3/2 sqrt(3)/2];
if ~trans
plot([center(1)-1 center(1)],[center(2) center(2)])
plot([center(1) center(1)+1/2],[center(2) center(2)+sqrt(3)/2])
plot([center(1) center(1)+1/2],[center(2) center(2)-sqrt(3)/2])
else %// exchange the two arguments to `plot`
plot([center(2) center(2)],[center(1)-1 center(1)])
plot([center(2) center(2)+sqrt(3)/2],[center(1) center(1)+1/2])
plot([center(2) center(2)-sqrt(3)/2],[center(1) center(1)+1/2])
end %if
end %for
end %for
plot([-15 15],[0 0],'-.') %// adjust length manually
plot([-15 15],[-15*sqrt(3) 15*sqrt(3)],'-.') %// adjust length manually
axis image
set(gca,'xtick',[])
set(gca,'ytick',[])
axis([-10 10 -13.3 13.3]) %// adjust axis size manually
set(gca,'Visible','off') %// handy for printing the image
例如,这是使用上述数据生成的图像:
