How to represent each entry of a matrix by its own box with matlab

Hey everybody I want to know if is possible to make a pcolor plot where the color values isn't stored on the edges of the boxes of all the little box but rather the middle of the little box. Right now I create my mesh with

x=0:50;
y=0:50;
[X,Y]=meshgrid(x,y);

and my figure with

figure
main=pcolor(X,Y,feldAIC);
colormap(cmap)
caxis([0 1]);
xlim([0 50]);
ylim([0 50]);

where cmap is my personal colormap vector and feldAIC is my matrix of the size [size(x),size(y)]. The result looks something like this:

but the shown colors must be some kind of interpolation between the four values on the corners of each little box. I would like to have something like this:

where each of my entry in my matrix feldAIC is represented by its own box and the color of the box is calculated by only the value of this entry.

So is there a way to make sure each entry is represented by its own box, rather then having each box be a interpolation of 4 entries.

what is the value of feldAIC? can you post the matrix so we can test the code?

[s.p4m]

for k=1:6
    for l=1:6
        feldAIC(k,l)=(k+l-2)/(k*l);
    end
end
x=0:5;
y=0:5;
[X,Y]=meshgrid(x,y);
figure
main=pcolor(X,Y,feldAIC);
caxis([0 1]);
ylim([0 5]);
xlim([0 5]);

You can use this as an example, but in reality the values for feldAIC are measured and don't follow any rules or any function.

I also did some quick scetches to help you understand what I want to accomplish

Now the values of the Box are calculated by the values of the 4 corners

But I want to have each box represent one value of my matrix.

You make all the four corner values same....

That won't work because then I would need to assign four different values of my old matrix to the same entry of my new matrix.

For example the entry (1,1) in my new matrix would need to represent the old values for (0,0),(0,1),(1,0) and (1,1) at the same time.

I found a script online which does exactly what I want

Thanks for the help

Try shading interp after pcolor.

[s.p4m]

I already thought about that, but that wouldn't change the fact that the values a represented by the corners and not the box itself.

Actually I am unable to find the difference between the images attached. Both the images looks same.
