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

I don't know what you mean with "plot this grid". Maybe something like this?
grid=reshape(0:99,10,10)';
figure, surf(grid)

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')
