Insert picture from file in pcolor cells - matlab

Question

I have a matrix a and I want to add pictures from my computer to certain cells whenever I display pcolor. I want to add pictures where the ones are. How would I go about that if the picture is in the same directory as the matlab file?
code:
a=[
1 0 0;
1 1 0;
0 0 0];
b=[NaN NaN NaN];
a = [a;b];
b = [b NaN];
b = b.';
a = [a b];
Cmap = [1 1 1];
colormap(Cmap);
pcolor(a)
I also have been noticing with pcolor that it shifts the matrix by 180 degrees, why is it that so?
This is the pcolor plot that I get:
I need something like this:
Here you see the image within pcolor cells, how can I accomplish this?

Answer 1

I will answer my own question this was what I did. I hope this can also help others.
a=[
1 0 0 0;
1 1 0 0;
0 0 0 0;
0 0 0 0];
aa = a;
ac = aa;
b=[NaN NaN NaN NaN];
a = [a;b];
b = [b NaN];
b = b.';
a = [a b];
I = imread('redirt.jpg');
J = imresize(I, 3, 'nearest');
[x , y] = size(aa);
delete(findall(gcf,'Tag','8puzzle'))
pos=get(gca,'position'); % getting the position
% calculating position
width=pos(3)/(y);
height =pos(4)/(x);
Cmap = [1 1 1];
colormap(Cmap);
pcolor(a)
axis off
% loop over the positions/cells you want to place image
for i=1:x
for j=1:y
if(aa(i,j) == 1)
% image position
axes('pos',[pos(1)+width*(i-1),pos(1)+height*(j-1),width,height], 'Tag','8puzzle');
% Show image
imshow(J)
end
if (i == 4 && j == 4)
axes('pos',[pos(1)+width*(i-1),pos(1)+height*(j-1),width,height], 'Tag','8puzzle');
% Show image
imshow('vacum.jpg')
end
end
end
set(gca, 'Ydir', 'reverse');
The image overlaps the cells just a little however, it is does not interfere with the display.
