How do i calculate for conditions

Hi,

I am trying to calculate actual evapotranspiration(AE) from my data. the conditions and calculation are as follows:

if P - PET > 0 
AE = PET
elseif P - PET < 0
AE = P - SMdiff

P, PET and SMdiff are all 12 x 1 double.

How do i compute this in matlab?

What about for loop?

I understand that you want code to calculate these conditions. I assume you are looking for a vectorized approach rather than a for loop. The code below should perform your calculations

AE = P>PET   %logical 12 x 1 array 
AE = AE.*PET + (~AE).*(P-SMdiff)

Thank you so much! This did exactly what I wanted.
