How can I extract the values from a 5000x2 matrix?

how can I extract the values from a 5000x2 matrix ( X and Y values) where the pairs of X and Y is (<-,-1) U (1, ->). So that I can a vector with the X values where the properties are fullfilled and a vector with the Y values where the properties are fullfilled.

clear;

clc;

rng(6039);

mu = 0;

sigma = 1;

n = 5000;

Xsim = normrnd(mu, sigma, n);

Ysim = normrnd(mu, sigma, n);

X = Xsim(:,1);

Y = Ysim(:,1);

XY = [X Y];

I do not understand the meaning of "(<-,-1) U (1, ->)"

Please use the methods to format code properly.

Maybe:

index = (X < -1 & Y > 1);
XY    = [X(index), Y(index)]

"Doesn't work" is not a useful description of a problem.

Perhaps you want this:

index = (X < -1 & Y < -1) | (X > 1 & Y > 1);
