Plot Population growth function with different values of b using for loop

I need to plot population growth model with different values of b
where b>d
and b=d
using for loops. Both results should be visible on the same graph with different colors.
Here is my function and intial value, but I am not getting how to get the plot .
H=@(t,N)[b*N-d*N];
[T,Y]=ode45(H,[0:1:time],[N0]);
Intitial value
b= 0.1 0.001
d=0.001
N0=400
I need two line for each b on the same plot.

f = @(t,b,d,N0) N0*exp((b-d)*t);
t = 0:0.1:10;
N0 = 400;
b = [0.1 0.001].';
d = 0.001;
plot(t,f(t,b,d,N0))
grid on

Maybe 400 looks like 0 in the loop plot because the second plot gives such large results for N.
Look at the plot from my code above. The red line looks like 0 because the blue line gets up to about 7e19, but is 400.
