else
 x(n)=(1-x(n-1))/(1-p);

Q4 = reshape(Q, 4, 4, numel(Q)/16);

After step 1 you have a set of 4x4 matrices. Now the text of step 2 is full of syntactical errors. I'm not sure, what it means. Maybe:

Q4 = reshape(Q, 4, 4, numel(Q)/16);
R  = zeros(size(Q4));
C  = [2,3,1,1; 1,2,3,1; 1,1,2,3; 3,1,1,2];  % You should be able to write this!
for k = 1:size(Q4, 3)
    R(:, :, k) = Q4(:, :, k) * C;
end

The part with the inversion matrix is not clear. Ask the one who has written the question.
