MATLAB: Cycle For how can i?

for cycle

Hello guys i have a matrix W(418*413) i need to do a "for cycle" that goes from 2:417 and that goes from 2:412 but instead of writing down the final number i want write "end-1" but when i write end it assumes that im ending the cycle of course, how can i write the right way so it can identify that it goes from 2 line till end-1.
P.e. for nx=2:412 but instead of writing 412 i want it "end-1"
          for ny=2:417 the same here.
end end

If i fully understand the question, below is the "cycle for loop" that you want,
 for idrow = 2:size(W,1)-1
    for idcol = 2:size(W,2)-1
       do stuff
    end
 end
