- Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
- Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
- Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.
How can I make this a callable function?

function [i,IS]=firststateupdate(N,P_ub,w1)
for i=1:N
w1=randi([0,1],1);
if IS(i)==2 && w1<P_ub
IS(i)=1;
end
end
end
Not enough input arguments.

Hey BAILEY,
I understand that you are trying to create and call functions inside the script.
I tried implementing this at my end and it is working fine. I am attaching the modified base code below:
N=10; % number of integrins
L=100; % size of the domain 100nm
D=.01; % diffusion coefficient
dt=1; % time step
F=randi([1, 10],1); % force on the bond with a random number of 1 to 10
P_a=randi([0,1],1); % binding rate of a random number from 0 to 1
P_ub=1/(1.5*F); % unbinding rate based upon our previous values
Tmax=500; % max time
% Intialize our integrins
x=randi([0,360],N,1); % x-coordinates generated randomily for each integrin
y=randi([0,50],N,1); % y-coordinates generated for each
state=ones(N,1); % Each integrin is set to an inactive state at 0
% our figure
figure;
axis([0 L 0 L]);
set(gca,'nextplot','replacechildren');
% position update
for t = 0:dt:Tmax
% colors for our integrin states
colors = repmat([1 0 0], N,1); % red for inactive state
colors(state == 2,:,:) = repmat([0 1 0],sum(state == 2),1);
% plotting our integrins
scatter(x,y,50,colors,'filled');
title(sprintf('Time=%.2f',t));
drawnow;
for i=1:N
w=randi([0,1],1);
if state(i)==1
dx=randi([-360,360],1);
dy=randi([-50,50],1);
x(i)=x(i)+dx;
y(i)=y(i)+dy;
quiver(x(i),y(i))
end
end
x=mod(x,L);
y=mod(y,L);
for i=1:N
w_1=randi([0,1],1);
if w_1 < P_a && state(i)==1
state(i)=2;
end
end
state=firststateupdate(N,P_ub,state); % Function Call
Displacement=sqrt((mean(x.^2))/N);
end
Also refer the modified function ‘firststateupdate.m’ that you were trying to create below:
function [IS]=firststateupdate(N,P_ub,IS)
for i=1:N
w1=randi([0,1],1);
if IS(i)==2 && w1<P_ub
IS(i)=1;
end
end
end
NOTE: When working with functions, ensure that you include all the input arguments used while defining the function before yuo call it.
