Hi everyone,

I currently have the below where N=140 In D1 I want half of the rows (i.e. 70 of them) to have a value >0 but <1, In D2 I want half of the rows (but not the same rows as D1 to have a value >0 and <1

Please can someone help around the best way of doing this?

D1=zeros(N,1); D2=zeros(N,1)

在 MATLAB Online 中打开

N = 140;
ind = randperm(N);
D1 = zeros(1,N);
D2 = zeros(1,N);
D1(ind(1:N/2)) = rand(1,N/2);
D2(ind(N/2+1:end)) = rand(1,N/2);
