What does the condition mean in Matlab, where x and y are the displacement that measures from [-1,1]
if (abs(x)>=1)
x=sign(x);
end
if (abs(y)>=1)
y=sign(y);
end

The code is checking to see if the values are out of range and if so moving them to the boundary.

You can easily run the code to see that it clips the values outside of [-1,1] so that they stay in this range. But it appears there is a typo in the y code. This line
x=sign(y);
should probably be this instead (note the y on the lhs)
y = sign(y);

If x > 1, it will assign x = 1
If x <-1, it will assign x = -1
If x is between -1 and 1, it will leave x unchanged.
Same for y (as long as you fix the typo)
