FIRST FUNCTION: function dydt=passiveinoutwithnumberofpumps (Np, D, Ao, y, x, s, t) dydt = Np*(D*((Ao-y)/x)*s);
In another script is: Np =0: 10; 20 ;30 ;40 ;50 ;60 ;70 ;80 ;90 ;100; D = 0.5; Ao = 0.7; x= 0.5e-6; s= 6e-6;
for i=Np [t,y]= ode23(@(t,y)passiveinoutwithnumberofpumps(i, D, Ao, y, x, s),[0 100],0);
plot (t,y) xlabel ('antibiotic treatment time') ylabel ('internal antibiotic') title ('passivein-out') end
then I click plot and get the graph that I want.
SECOND FUNCTION: function T=ribosometarget (T,l,r,k)
% CK % 05/3/2018 % This functions calculates the ribosome targets by gentamicin
r=0.1; l=[0:10:100]; k=4.5E-3;
T=r+(l/k)
plot (l,T)
xlabel ('specific growth rate')
ylabel ('ribosomal target')
title ('ribosome target available for gentamicin at different specific growth rate')
How do I combine both function and plot them into 1 graph where S=(Np*(D*((Ao-y)/x)*s))/(r+(l/k))

Take a look at the "hold" command. You can create your first plot as you have, then use "hold on" to tell Matlab that you'd like to add another data series to the axis. Then plot your second item, followed by "hold off"

I am not certain what you want.
Try this:
passiveinoutwithnumberofpumps = @(Np, D, Ao, y, x, s, t) Np*(D*((Ao-y)/x)*s);
Np = 0 : 10 : 100;
D = 0.5;
Ao = 0.7;
x= 0.5e-6;
s= 6e-6;
tv = linspace(0, 100, 25);
for i = 1:numel(Np)
[t(:,i), y(:,i)]= ode23(@(t,y)passiveinoutwithnumberofpumps(Np(i), D, Ao, y, x, s),tv,0);
end

% This functions calculates the ribosome targets by gentamicin
r = 0.1;
l = 0:10:100;
k = 4.5E-3;
T = r+(l/k);
S = (Np.*(D*((Ao-y)/x)*s))./(r+(l/k));
figure(1)
subplot(2,2,1)
plot (tv,y)
xlabel ('antibiotic treatment time')
ylabel ('internal antibiotic')
title ('passivein-out')
grid
subplot(2,2,3)
plot (l,T)
xlabel ('specific growth rate')
ylabel ('ribosomal target')
title ('ribosome target available for gentamicin at different specific growth rate')
grid
subplot(2,2,[2 4])
surf(l, tv, S+1E-4)
set(gca, 'ZScale','log')
view(-130, 15)
xlabel('L')
ylabel('T')
zlabel('S')
grid on
set(gcf, 'OuterPosition',[150 150 1100 550])
Experiment to get the result you want. (I am using R2017b, so this should work with all recent versions.)
