I have a variable 'n'. I want n to take a value 1 or 2 randomly. how do i code it?

I have a very basic question.

The thing is I want to run a loop and each time the loop runs, n should take the value either 1 or 2 randomly.

Aanandita - use randi to generate a random integer between 1 and a maximum integer of your choice. If you want the random integer to be one or two, then just do

 n = randi(2);

Answer 2

This works:

N = 6;
for k1 = 1:N
    n(k1) = randi(2);
end

although you can do the same thing much more efficiently in one line without the loop:

n = randi(2, 1, N);

[Aanandita Katre]

So is N the number of times the loop runs? As in here the loop will run 6 time right?

[Star Strider]

Correct.

I set ‘N’ to be a variable to make the code easier to modify to do what you want.
