MATLAB: How flip the signal as below

bipolarcomplexdspDSP System ToolboxfftifftMATLABunipolar

X=[1 2 -5 4 -7 8 9 -4 -5 6 1 -2 3 -6 ]

I want to program the following using "if"

If the value of Xp is higher than "0", pass the signal

But if the value of Xp is less than "0", make it equal to "0"

If Xn is less than "0", pass the value

If Xn is higher than "0", make it equal to "0"

After finishing the program

flip the negative signal

Pass the flip negative signal successively after the positive signal

MATLAB: Separate the positive values from the negative values

Xp=X(X>0)
Xn=X(X<0)
Xn=abs(Xn)

MATLAB: How reshape the separated signal to original signal

YOu pick the indices and get what you want.

x= [1 2 -6 9 -7 8 -8 -5 2 4 -6 4 -4 -5 -7 6 10 2 3 7 -8 9 -8 -5 4 -6]
Xp=x(x>0) ; idxp = x>0 ; 
Xn=x(x<0) ; idxn = x<0 ;
% after separated the signal is transmitted 
fr=[length(Xp), Xp, Xn]
% then in the recevier Rx
rp=fr(2:fr(1)+1);       % positive Rx
rn=fr(2 + fr(1):end);   %negativ Rx
iwant = zeros(size(x)) ;
iwant(idxp) = rp ;
iwant(idxn) = rn ;

Note that, the above code can be optimized by using completely indices.
