Maximum recursion limit error

I keep getting this maximum recursion limit error.

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware

that exceeding your available stack space can crash MATLAB and/or your computer.

Error in ode45

I have attached my code too. Please can you help me to fix it.

ode45 should be called outside the ODE function. Your actual ode function is this

function dv=Question3(t,v)
% dv/dt=8-4
dv=4;
end

and then you need to call ode45 from a separate script

to=0;
tf=100;
tspan=[to tf];
v0=0;

[t,v]=ode45(@Question3,tspan,v0);

plot(t,v(:,1));
xlabel('Time(s)');
ylabel('Volume(l)');
