how to plot a 10*10 grid map and how to number the grid cells? (sample pic is attached here)

Guys, I am in learning phase of matlab. I don't know how to plot this type of grid? i knew plotting simple grids, but this one made me mad. Is it possible to make this kind of one? I attached the model of the grid. thanks guys

I have a model that i wrote already, try to compare it with Joseph's method.

   [X,Y]=meshgrid(1:11);
figure; hold on;
plot(X,Y,'k');
plot(Y,X,'k');axis off
I=(rand(11));
surface(I);
h=linspace(0.5,1,64);
h=[h',h',h'];
set(gcf,'Colormap',h);
N=100:-1:1;q=1;
x=linspace(1.5,10.5,10);
y=linspace(1.5,10.5,10);
for n=1:10
    for p=1:10
        text(y(n)-.5,x(p),num2str(N(q)),'FontWeight','bold');
        q=q+1;
    end
end

thanks youssef,,,your coding is simple and i can understand easily...i have one question..if i like to make some grid in black& white color what i have to do?? i tried with colormap command but it gives entire figure as black

[Youssef Khmou]

try :

   K=randint(10); % colormap gray

I don't know what you mean with "plot this grid". Maybe something like this?

 grid=reshape(0:99,10,10)';
 figure, surf(grid)

thanks for your reply.. i like to create 10*10 grid with cells labelled in numbers.that's all

[ANDREA DI MARTINO]

Hi, how I can create an undirected graph with grid=reshape(0:99,10,10)';?

I need to create a grid graph 10x10 with undirected edges.

you can use the text() to insert the grid labeling. here is an example. this is for labeling 1x1 pixels but it is scalable for larger grid sizes.

%something in the background
I = magic(10)

%generate where each text will go
[X Y]=meshgrid(1:10,1:10);

%create the list of text
string = mat2cell(num2str([1:10*10]'),ones(10*10,1));

%display the background
imagesc(I)
hold on

%insert the labels
text(Y(:)-.5,X(:)+.25,string,'HorizontalAlignment','left')

%calculte the grid lines
grid = .5:1:10.5;
grid1 = [grid;grid];
grid2 = repmat([.5;10.5],1,length(grid))

%plot the grid lines
plot(grid1,grid2,'k')
plot(grid2,grid1,'k')

preferably don't call your variable 'grid' though even though in this case you are unlikely to want to use the grid function.

[Joseph Cheng]

true... i wrote it up in a couple of min. wasn't really thinking when i did it.

[Youssef Khmou]

That is an efficient technique to generate a figure .

thanks joseph... it was useful to me..going to try my own logic.
