Can anyone help me identify what is wrong with this code

function l =pol3(arr)

arr = [5 10 15 20 25 30 35 40];

for i=1:length(arr)

diff(i) = arr(i+1) - arr(i) %I keep getting an error on line 4

end

Try this instead —

for i=2:length(arr)

diff(i) = arr(i) - arr(i-1) %I keep getting an error on line 4

end

Be sure that ‘diff’ — not ‘l’ — is defined as the output.
