Hi, guys, I want to generate s sequence of two random numbers r1 and r2 satisfying the condition 0<r1<r2<1. How to do it using MATLAB. Your response is highly appreciated. Thank you!

The easy way...but that also yields r1 < .5 and r2 > .5 is:
N = 99; % Or any other number but 99 is my go-to number of observations
r1 = rand(N,1)*.5;
r2 = randn(N,1)*.5 + .5;

N = 10;
r = sort(rand(N,2),2)
r = 10×2
0.0901 0.9582 0.2136 0.7758 0.7603 0.9945 0.0893 0.8684 0.2264 0.4635 0.2086 0.7458 0.6878 0.9048 0.3360 0.7293 0.2467 0.6758 0.2907 0.5876
