How to make a variable negative if another variable is negative?

16 views (last 30 days)
I have two columns (X & Y) full of numbers 200 numbers in a text file.
All values of X are positive, while the values of Y are mixed with negative and positive numbers.
I'm trying to create a simple if statement, so change all of the X values that correspond to a negative Y value, to negative.
This code does not work though:
Code:
if Y < 0
X1 = X*(-1)
end
Unrecognized function or variable 'Y'.
