Use the reshape function, specifically:
Out = reshape(A, [], 2)'
producing (for the vector you posted):
Out =
0 0 0 1 1 0 1 0
0 0 1 1 0 0 0 1

if I have code like this =
a = randi ([100 200], 4000,8);
b = de2bi(a);
c = b(:);
how to make the C matrix back into the B matrix?

I do not have the Communications Toolbox. I cannot run your code.
