% I need different "In" on every stage and key in each stage would be ciphertext of previous stage
clear all;
clc;
Key = randi([0,1],[1,4])
In1 = randi([0,1],[1,4])
Ciphertext1 = xor(Key,In1)
Key1 = Ciphertext1
In2 = randi([0,1],[1,4])
Ciphertext2 = xor(Key1,In2)
Key2 = Ciphertext2
In3 = randi([0,1],[1,4])

Use a cell array to store the values:
for k = 1:16
Key{k} = randi([0,1],[1,4]);
In{k} = randi([0,1],[1,4]);
Ciphertext{k} = xor(Key{k},In{k});
end

thanks for fast reply. But, I need different "In" on every stage and key in each stage would be ciphertext of previous stage
