How would you plot this ODE in matlab?
dB/dt = r(t)*B-k(t)

Not enough information, so I created the missing variables:
tv = linspace(0, 100, 25); % Time Vector Common To ‘r’ And ‘k’
rv = randn(1,25); % Create ‘r’
kv = randn(1,25); % Create ‘k’
ODEfcn = @(t,B) interp1(tv,rv,t)*B-interp1(tv,kv,t);
B0 = 4.2;
tspan = [0 15];
[T,B] = ode45(ODEfcn, tspan, B0);
figure
plot(T,B)
grid
This runs without error.
Experiment with the actual vectors for ‘r’ and ‘k’ to get the correct result.
