I have a vector:
[R1,R2]= Where R1 = 7 3 3 5 3
R2 = 5 5 5 4 6
I want to randomly select one of these pairs, like [7,5]. How I can do this in Matlab?

idx1=randi(numel(R1))
idx2=randi(numel(R2))
out=[R1(idx1) R2(idx2)]

c1 = randi([1 numel(R1)],1,1)
c2 = randi([1 numel(R2)],1,1)
result = [R1(c1) R2(c2)]
or
result = [R1(c1) R2(c1)]
