Hi,
I would like to display max and min value on my colorbar.
How can I do it?
In my plot it only displays 0.01, 0.02, 0.03...
I want to display max and min also on the colorbar.
Thanks.

h=colorbar
t=get(h,'Limits');
set(h,'Ticks',linspace(t(1),t(2),5)

You need to also set the TickLabels properties.
Could you confirm that you are using R2014b or later? It appears likely you are as Ticks was not a property of colorbars from R2014a and before.

You can also do the following and keep the automatically selected tick marks.
hColorbar = colorbar;
set(hColorbar, 'Ticks', sort([hColorbar.Limits, hColorbar.Ticks]))
This simply adds the limits to the tick labels and sorts them in order so they don't error out.
If you want them to be the same display precision (digits shown) as the others, you can do the typical:
round(0.00532 * 1000) / 1000
Obviously change the 1000 to whatever value you need to get whatever digit you need to round off to the one's place value for the rounding function. The /1000 gets it back in the original units.
