I want to pair two numbers randomly in each pair as [ 5 8] [ 11 4] [3 17] .....

Are repeats, either in the same row or in different rows, allowed? Or do all numbers need to be different? Must the numbers be integers, or can they be floating point/fractional?
Is this homework?

hi ananya,
it is my understanding that you want to create a array of pairs with random vaues. but is there any constraints like the range or max value.
anyways if there is a value try this
a=20;
idx=reshape(randperm(a,[],2);

Say you want to pair numbers randomly between 1 to 20.
n = 10 ;
iwant = zeros(n,2) ;
for i = 1:n
iwant(i,:) = randperm(20,2) ;
end
iwant
iwant = 10×2
11 8 16 14 8 1 20 18 11 6 6 20 4 18 15 14 5 3 18 2
