Hi, I have a array, for example, [0 0 0 0 ]
And I want each of them to be randomly adding 0.4 or subtracting 0.4
How do I do that?

n=4; % array length
x=zeros(1,n); % sample array
d=0.4; % value to be added/subtracted
k=rand(1,n); % uniformly random number between 0 and 1
x(k<0.5)=x(k<0.5)-d; % subtraction
x(k>=0.5)=x(k>=0.5)+d; % addition
many other ways are possible
