I have a random number generator when the input selects the interval length and only runs it if it is between 50 and 200. I was wondering how do I round the output of random numbers so that they are only integers?(ex. 0,1,2,3,4,5,6,7,8,9 )

在 MATLAB Online 中打开

n= input('Enter Vector Size');
if n>=50 && n<=200
    R= [0,1,2,3,4,5,6,7,8,9];
z = rand(n,1)*range(R)+min(R)
else 
    disp('Pick a Correct Vector Size')
    n= input('Enter Vector Size');
    R= [0,1,2,3,4,5,6,7,8,9];
z = rand(n,1)*range(R)+min(R)
end

Have you considered just using randi() ?

ps: what if someone enters a bad vector size twice in a row?

"I was wondering how do I round the output of random numbers so that they are only integers?"

Two easy solutions:

Use randi, which returns integers.
Round the values using round, ceil, fix, or floor.
