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.
