How to produce 1 and -1 in MATLAB

Hello all, I want to generate 2000 numbers out of which 50% times it should be +1 and for remaining 1000 it should be -1.

Any help in this regard will be highly appreciated.

Exactly 50% or randomly?

x = randi([0, 1], 1, 2000) * 2 - 1;

y = [ones(1, 1000), -ones(1, 1000)];
y = y(randperm(y));
