MATLAB: How to plot an ODE

Question

Silly question but how can I plot a simple ODE like the following?

My ODE is:

dy/dt=1-(t/n)-y

where n is an array

n=[1 2 3 5 Inf]

Answer 1

Use for loop to solve equation 5 times for each n

n = [1 2 3 5 inf];
f = @(t,y,n) 1-t/n+y;
for i = 1:length(n)
    [t,y] = ode45(f,[0 5],ic,[],n(i));
    line(t,y)
end
