if
x=[1 2 -5 7 -9 4 -6 7 -6 8 -5 2 -1 5 -6 -8 -9 7 4 -1 ]
x + = if x(k) ≥ 0
0 otherwise
x-= if x(k) < 0
0 otherwise
. The positive signal x +(k) is transmitted in the first subframe .
the second subframe is used to carry the flipped (inverted polarity) signal −x −(k)
then send full signal

You question is not very clear to me, but for the first part of it, I belive you want to this:
x=[1 2 -5 7 -9 4 -6 7 -6 8 -5 2 -1 5 -6 -8 -9 7 4 -1];
y=x+(x>=0)*2-1
