Hello all,
I don't really know how to ask this question, but I'll try my best.
From a 20*20 matrix I used griddata and then pcolor to plot a figure just like this one:

I now would like to insert the matrix as text on top of the figure (just like you can see in the link above).
Of course I can use the "text" function and insert all the values one by one. But I'm sure there is an easyer way to do it!
I tried using clabel, but I couldn't find a way to label all the matrix values.
Your help would be much appreciated!
Paul

You could do all the text commands in a loop, for example:
A = randn(20);
x = linspace(0,1,20); y = x;
pcolor(x,y,A); colormap summer
for ii=4:4:16
for jj = 4:4:16
text(x(ii),y(jj),num2str(A(ii,jj),2))
end
end

Thank you Andrew for your reply.
After I asked the question I spent some more time thinking about it and found the exact solution for my problem. I hadn't had time to put it here.
Sometimes the best solution is the simpler.
Best regards,
