I want to make an array containing only the values 1 and -1. It should be randomly generated so as to get a random number of occurences of both values.
I made the following but I feel like its way too complicated. Is there a simpler way? thanks
x = randi ([-1,1],1,n) ;
for k = 1 : n
if x (k) == 0
r = rand ;
if r > 0.5
x(k) = 1 ;
else
x(k) = -1;
end
end
end
