For an assignment I need to give the percentage difference or change between an initial and final value. It is about a distribution of a 27 city model as in the picture. Is it possible to calculate all those differences with one command? Thanks.

Never mind, I just found the excel file which was saved after the run. However, is there a way to do it?

It depends on how you want to define it.
This works:
pct_change = 100*(final-initial)./initial;
This is vectorised, so you can use it with vectors of ‘initial’ and ‘final’.
