Generating an Array of Hexagonal Shape Pattern
显示 更早的评论
Hi,
Here I have added a simple code, modifying my previous post (sorry for my repost, as I am trying to make my question much more understandable). The following code generates an array of values (i.e. H matrix here) having a dimension of 256x256 which is a square matrix (pattern looks like some black and white strips). I would like to modify this square matrix into a regular hexagonal shape through Matlab code. I have no idea how to do this,so can anyone plese help me in this regard?
Code:
mx=5;
my=10;
[x, y]=meshgrid(-1:2/255:+1, -1:2/255:+1);
H=(cos((x*pi*mx)+(y*pi*my)))>0;
figure(1)
imagesc(H); colormap gray; axis image; axis off

I used patch to create a hexagonal grid.
% MWE %
l=10;
b=10;
C=rand(l,b);
xhex=[0 1 2 2 1 0]; % x-coordinates of the vertices
yhex=[2 3 2 1 0 1]; % y-coordinates of the vertices
for i=1:b
j=i-1;
for k=1:l
m=k-1;
patch((xhex+mod(k,2))+2*j,yhex+2*m,C(k,i)) % make a hexagon at [2i,2j]
hold on
end
end
axis equal
Note that this code will generate hexagons at [2i,2j] co-ordinates. You can rescale the axis (TickLabels) or rescale the vertices of the hexagon. The mod(k,2) is used to shift the hexagons by 1 in alternate rows so that they fit. I have used a random matrix. You can simply change the matrix C to your data and plot the grid accordingly.

I think they are not hexagon. The distances between the center and the corners are not constant.

Sim Mah, they are hexagon, just not regular hexagons.
