I need to change the colorbar label to the position showed in the attached image.
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
clims = [4 18];
imagesc(C,clims)
e=colorbar;
e.Label.String = 'amp';

Ran in:
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
clims = [4 18];
imagesc(C,clims)
e=colorbar;
e.Label.String = 'amp';
%Adjust the position of the label
e.Label.VerticalAlignment = 'middle';
%The positioning, in the default unit, of the text label
%is corresponding to the values of colorbar
%x value is Middle of the colorbar i.e. 0.5
%y value is slightly above the top limit of colorbar
e.Label.Position = [0.5 clims(2)+0.75];
Edit - If you want to make the text horizontally aligned, change the rotation to 0 by using the command below
e.Label.Rotation = 0;

There seems to be a hidden Title property on the ColorBar object that might be a better way to accomplish this. Just do
h = colorbar;
h.Title.String = 'amp';
Note that h.Title will not appear until set.
