Can you elaborate more? Is the output xn as cell array or ???
Expected result look like???

Far too little information here.
Are these complex numbers? Are they random, or ar they in some specific order?
As far as creating them, this is just a vector if they are to be complex numbers, or it is an nx2 array. In either case, the answer is trivial, or it should be. But only you have any idea of what you want.

Some programs such as Python use j as the imaginary unit (Matlab uses i). Could it be that (±1, ±j) represents an imaginary number?

That helps but the problem is still not defined well enough to offer a definite solution.
xn ∈ {(±1, ±i)} means xn is an element of the set [-1-i, -1+i, 1-i, 1+i].
I don't know how n or N come into play, though.
Here's an idea I'm pulling out of thin air:
% Create a column vector n:N +/- [1 +/-i]
n = 1;
N = 100;
xn = reshape((n:N)' + [-1-i, -1+i, 1-i, 1+i],[],1);
*This uses implicit expansion which requires Matlab r2016b or later.
