Generate a Hexagonal Array

How can I make a hexagonal arrangement? I have a series of data that make up an array and I want to express it as a hexagonal map like figure.

Thanks a lot

i have this problem too. Did you solved it?

@davod naghavi, we don't know. He never accepted any of the answers below. But since it's been over 3 years, I'd assume it was solved. And I doubt he'll answer you. Regardless, you can also look at the answers below and get your own solution.

Thank you Dear @Image Analyst

Answer 1

It's been talked about a lot before. Just search for it: https://www.mathworks.com/matlabcentral/answers/?term=tag%3A%22hexagon%22 and I'm sure you'll find code that you can adapt.

base=1;
X=[];
Y=[];
for num=1:6
    x=zeros(num*6,1);
    y=zeros(num*6,1);
    x(1:6)=base*num*cos(2*pi/6.*(0:5));
    y(1:6)=base*num*sin(2*pi/6.*(0:5));
    if num>1
        for q=1:num-1
           start_x=x(2)-q*base;
           radi0=sqrt(start_x^2+y(2)^2);
           start_alpha=1/3*pi+pi*1/3*1/(num)*q;
           x(q*6+1:q*6+6)=radi0*cos(start_alpha+pi/3.*(1:6));
           y(q*6+1:q*6+6)=radi0*sin(start_alpha+pi/3.*(1:6));
        end
    end
    X=[X; x];
    Y=[Y; y];
end
scatter(X,Y)

@Stijn Haenen Thank u . but i need as an n*n Array.

[Image Analyst]

@davod naghavi, what do the rows and columns represent? Give an example of what you want.

I have a matrix like the attachment. I want to have a figure with surf and a hexagonal meshes.Its the problem!

@Image Analyst, I have a quite same problem. I actually want to make an nano-particle array with hexagonal symmetry. I need it in my project called fourier plane imahing microscopy. i need to analyse the fourier plane image. so during the pandemic i have only one option that is to simulate it. can you help??

Hi everyone,

The problem raised above I had done it with another account a few years ago. I found a solution using the scatteredInterpolant function in Matlab. Here I share a code in case it can help you.

Thanks in advance.

figure('rend','opengl','pos',[400 200 1024 720]);
% X -> vector (x coordinates)
% Y -> vector (y coordinates)
% Z -> vector (reactor power values)
% These arrays were taken from the simulation code

F = scatteredInterpolant(X,Y,Z,'nearest');
[X,Y] = ndgrid(linspace(min(X),max(X),1500),linspace(min(Y),max(Y),1500)); 
Z = F(X,Y); 
POWER_map = surf(X, Y, Z, 'edgecolor', 'none');
R_FA = lattice_pitch/2;
Rx_Core = 11*R_FA;  % Core radius
limitx = Rx_Core ;
ylim([-limitx limitx]);xlim([-limitx limitx]);
axis('square','off')
colormap('jet')
box off
grid on
view(a,90); % Vista en XY

% If you want to add values to each hexagon

xtext = COORDX(:,i);
ytext = COORDY(:,c);
ztext = POWER_FULL_CORE;
ztext(ceros) = NaN;
strmax = num2str(ztext,3);
t2 = text(xtext,ytext,ztext,strmax,'HorizontalAlignment','center','VerticalAlignment','middle', 'FontSize', 10);

Nice. Depends on what form @Yrobel Lima wants though. There is also a new nsidedpoly() function that might be what someone wants.
