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;
