Not enough input arguments!

Hi! I am so new to matlab and could really use some help.

I have two separate files. I am getting a "not enough input error" for my for loop and am not sure why. Thanks

from first file:

x0 = 0.7; 
iters = 30;
r = 2.5;
x = logistic_map(x0,r,iters);
x1 = x;
r = 3.2;
x = logistic_map(x0,r,iters);
x2 = x;
r = 3.52;
x = logistic_map(x0,r,iters);
x3 = x;
r = 4;
x = logistic_map(x0,r,iters);
x4 = x;

From the second file:

function x = logistic_map(x0,r,iters)
row_num = 1;
for i = 1:iters
    x(1,:) = x0;
    row_num = row_num + 1;
    x_new = r*x0*(1 - x0);
    x0 = x_new;
    x(row_num,:) = x_new;
end

I am getting an error for the second file

Not enough input arguments.
Error in logistic_map (line 11)
for i = 1:iters

Thank you!

It says line 11 but there are 10 lines of code in your function. Where is the rest?

oh sorry, they were comments I deleted. line 11 is actually line 3

Your entire code runs for me without error.
