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

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

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

Above 2 statements are exactly same if I assume

Xp = X;
Xn = -X;

If these statements are same then, why do you need to "filp" the signal ?
