How to plot an ODE?

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]

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

This syntax of ode45 is obsolete and no longer documented. Using new documented syntax will avoid any confusion for the readers

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

Even for the obsolete syntax, the correct line is

[t,y] = ode45(f,[0 5], ic, [], n(i));

Don't know what you are talking about

Sorry!! I pasted the wrong code.

Is there a way to make each line a different color?

[darova]

Of course

line(t,y,'color',rand(1,3))

Thank you, kindly, sir!
