Randperm in for loop

I am using RANDPERM to select 1 unique number from the following matrix [2 3 4] per each cycle of a For loop. I want RANDPERM to give a different number each for loop cycle, but first it gives 2, 3 at least one time but then is just giving 4 for the rest of for loop cycles. I already tried using "RGN SHUFFLE" but it doesn't work as it still does the same thing. Any suggestion?

Thank you!

I am not sure how you are using randperm, but it should not be needed in this case. Something like the following will work

x = [2 3 4];

for i = 1:10
    idx = randi(numel(x));
    rand_val = x(idx)
end
