Plotting a confusion matrix (without using plotconfusion) with large values

I am trying to plot this confusion matrix:

A = [1195   3  54;
        0 631  34;
       90 135 158];

I cannot use plotconfusion as I do not have access to NNT. I've tried to use colormap and imagesc, but have had no luck. Are my values too large? If they are, what do you suggest? Thank you.

Perhaps you mean this:

A = [1195   3  54;
  0 631  34;
  90 135 158];
imshow(A, [], 'InitialMagnification', 1600);
colorbar;
axis on;
% Set up figure properties:
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
% Get rid of tool bar and pulldown menus that are along top of figure.
set(gcf, 'Toolbar', 'none', 'Menu', 'none');
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off')

What does "plot" mean to you? You can display the values of A simply by putting the letter A on its own line of code. Did you want some other kind of display?
