代表在移动通信系统中使用的蜂窝网络的六边形网格 [英] Hexagonal grid representing a cellular network as used in mobile communication systems

问题描述

我对Matlab来说还比较陌生，我想生成一个六边形网格，该网格代表一个蜂窝网络，其中每个六边形都有特定的行为.

I am relatively new to Matlab and I want to generate a hexagonal grid that represents a cellular network where each hexagon has a specific behaviour.

我的问题是如何从方格变为十六进制格(传递矩阵)?这就是我到目前为止所拥有的.

My question is how does one go from a square grid to hex grid (transfer matrix)?. This is what I have so far.

[X,Y] = meshgrid(0:60);
figure(1), plot(X,Y,'b')
hold on, plot(Y,X,'b')
axis square

推荐答案

几年前，我写了一些代码来做到这一点:

A few years ago I wrote some code to do just that:

%// 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，这是使用以上数据生成的图像:

For example, this is the image generated with the above data:
