how apply parfor for this code

Hi friends ....
i try apply parfor for my code but appear note " the parfor loop cannot run........"
Are there any solution?
This code:
lfSeed = '11001011';
lfPrev = lfSeed;
lfsrKey = uint8(zeros(m, n));
parfor i=1:m
for j=1:n
%LFSR Sequence
lfPrev = strcat(lfPrev(2:8), num2str(xor(str2double(lfPrev(1)), xor(str2double(lfPrev(5)),....
xor(str2double(lfPrev(6)), str2double(lfPrev(7)))))));
lfsrKey (i, j) = bin2dec(lfPrev);
end
end
lfsrKey (:,:, 2)=lfsrKey (:,:, 1);
lfsrKey (:,:, 3)=lfsrKey (:,:, 1);
toc;

No, parfor cannot be applied here. Your loop iterations are not parallel because lfPrev depends on previous iterations.
