MATLAB: How to assign randomly generated numbers to a matrix say 10 by 2

random number generator

i have created random numbers using the code k1=randi([1,1000],1,10) Now how to assign this 10 randomly generated numbers to a matrix 10 by 2 with repetition allowed.

Best Answer

X = randi([1,1000],10, 1);
while true
  M = [X, X(randperm(length(X)))];
  if all(diff(M,2)~=0); break; end
end
The while loop removes the possibility that a number is matched with itself.
