this is the block diagram



my code is like this:

function [ y1,y2,D1,D2 ] = Encoder(input)
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
length_input = length(input);
y1(1) = input(1);
D1(1) = 0;
D2(1) = 0;
y2(1) = input(1);
for i = 2:length_input
y1(i) = input(i);
y2(i) = xor(input(i),D2(i-1));
D1(i) = xor(y2(i-1),input(i));
D2(i) = xor(D1(i-1),y2(i-1));
end
end

i insert a group of date [1 1 0 1 1 0 0 0]

using the state machine ,the output should be [11 10 01 10 10 01 00 01]

but i run my code and got a set of wrong output which is [11 11 01 10 11 00 00 01]

could you please see if there is any problem in my code?

it might be easier to draw the state machine instead of writing it out textually. Stateflow (another product by MathWorks, makers of MATLAB and Simulink) is probably the best tool to represent state machine logic like this. Look at some of the getting started videos on the Stateflow website:
