function [y,x]=position(N,IS)
for i=1:N
if IS(i)==1 % checks if ligand is active and give new position
dx=randi([-360,360],1);
dy=randi([-50,50],1);
x(i)=x(i)+dx;
y(i)=y(i)+dy;
end
end
The errors are this
Not enough input arguments.
Error in position (line 4)
if IS(i)==1 % checks if ligand is active and give new position

Did you assign the input arguments before you called it, liks
N = 5;
IS = ones(N, 1);
[y,x]=position(N,IS)
Probably not. You probably just clicked the green run triangle without sending in any input arguments. You can't do that if input arguments are required. You must assign them and pass them in. You can do this in the command window or a script.
