How to properly plot data points

Hi, I need to know the proper way I should plot my data such that I do not have to plot within the for loop, and so that the points will connect with a line.

clc
clear

SO = 8; 
vm = 0.7; 
ks = 2.5; 

F =@(sm,t) SO-vm*t+ks*log(SO/sm)-sm; 

sl = 0;
su = 9;

n = 6; 
es = 0.5*10^(2-n); 

for t = linspace(0,40,50)
   sm = michaelis_menten(sl,su,es,t,F); 
   hold on; 
    plot(t,sm,'-'); 
    hold off; 

end

xlabel('Time(day)'); 
ylabel('Subtrate Concentration (moles/L)'); 
title('Substrate Concentration vs Time');

the function michaelis_menten is

function sm = michaelis_menten(sl,su,es,t,F)
ea = 1; 
so = 1*10^8; 

while ea > es

      sm = (sl+su)/2; 

      if F(sl,t)*F(sm,t)< 0
          su =sm;
      elseif F(sl,t)*F(sm,t)>0
          sl = sm;
      else
         so = sm;
      end

      ea = 100*abs((sm - so)/sm); 
      so = sm; 

end 

end

Here's one way:

numberTimes = 50;
t = linspace(0,40,numberTimes);

figure
for nt = 1:numberTimes
   sm(nt) = michaelis_menten(sl,su,es,t(nt),F); 
end
plot(t,sm,'-'); 
xlabel('Time(day)'); 
ylabel('Subtrate Concentration (moles/L)'); 
title('Substrate Concentration vs Time');

If your subfunction could be vectorized (which I did not check), you could avoid the for-loop completely.
