multiple imagesc plot with one colorbar in matlab

How should I plot 10 square size imagesc plot in matlab? All of them has same x and y limit. I want to plot in two horizontal
lines in which in the first line I will plot 5 square size imagesc plot side by side and in the downward line,
I will plot the rest 5 imagesc plot. I want to include one colorbar in the east side which matches 
the size of upper line and lower line of the plots?
