Reposition colorbar or subplots

I am trying to get a colorbar to reside to the right-hand-side of a series of four subplots. I'm using this code but the bar intersects with the last image as shown in this fig problem

ax(1)=subplot(1,3,1);imagesc(stats.mean,[0 1]);colormap(jet(256)); title('mean');
ax(2)=subplot(1,3,2);imagesc(stats.median,[0 1]);colormap(jet(256)); title('median');
ax(3)=subplot(1,3,3);imagesc(stats.std,[0 1]);colormap(jet(256)); title('std');
h=colorbar;
set(h, 'Position', [.8314 .11 .0581 .8150]);
for i=1:3
pos=get(ax(i), 'Position');
set(ax(i), 'Position', [pos(1) pos(2) 0.85*pos(3) pos(4)]);
end;

I suggest a different approach.

Suppose you are plotting the following:

ax(1) = subplot(1,3,1);imagesc(rand(100,1),[0 1]);
ax(2) = subplot(1,3,2);imagesc(rand(100,1),[0 1]);
ax(3) = subplot(1,3,3);imagesc(rand(100,1),[0 1]);

I recommend simply resetting the dimension of the third subplot which will be affected by colorbar and stretching the figure to include the added colorbar.

% Get positions of all the subplot
posa = get(ax,'position');
h    = colorbar;

% Reset ax(3) position to before colorbar
set(ax(3),'position',posa{3})

% Set everything to units pixels (avoids dynamic reposition)
set([ax h],'units','pix')

% Widen figure by a factor of 1.1 (tweak it for needs)
posf = get(gcf,'position');
set(gcf,'position',[posf(1:2) posf(3)*1.1 posf(4)])

The result
