[ferret_users] Looping over arrays

["Balaguru, Karthik" <karthiknaidu@xxxxxxxxxxxx>]

   Hi all,

      I have a problem with arrays in ferret. I have an array with three colums [x(i) y(i) l(i)], which are lat, lon and time respectively. The problem is they are not continuous, i.e; for each i, x,y and l are random. I have the corresponding sst data.
Now for i=1:n I want to read in the array data and then calculate the sst change, like 

 sst_change(i) = sst(x(i),y(i),l(i) + 1) - sst(x(i),y(i),l(i) + 1)

      It'll be great if somebody can help me out with this. Thanks!


   Truly,
   Karthik.
