I am trying to execute this code but it gives me an error Index exceeds array bounds.

  I= [234, 112, 22, 56; 78, 81, 119, 121; 98 193 250 211; 33 135 199 201];
  s=[110 45 32; 95 150 67; 89 76 55];
  s2= s(I+1)

What you are doing is wrong. You are trying to access more number of elements from s. What exactly you want to do?

I am applying sbox on an encrypted image.
