Changing the number format of colorbar values

My color bar values are huge and I would love to maximize on the plot space. How can I change the values of my colorbar to say value * 10^8. Thanks

Which MATLAB version? The methods are different from R2014b onwards.

In R2014b or later, colorbar objects have a http://www.mathworks.com/help/matlab/ref/colorbar-properties.html TickLabels property and also a TickLabelInterpreter. So you could for example,

cb = colorbar();
set(cb, 'Ticks', [10^7, 2.5*10^7, 5*10^7, 7.5*10^7, 10^8], 'TickLabels', {'10^7', '2.5 x 10^7', '5 x 10^7', '7.5 x 10^7', '10^8'}, 'Interpreter', 'tex')

Works perfect. Thanks.
