using euler method for population growth

I dont know how i would write this formula using the euler method
dp/dt=G(Pmax-P(t))*p(t)
Plot the population as a function of time from t = 0 to t = 20 years
Use the following values for constants in the differential equation: o pmax = 10,000 o G = 0.00005
Use an initial condition of p = 800 when t=0

Is P(t) different than p(t) ?
I recommend you look at ode45()
Reminder: MATLAB has no implied multiplication. All multiplication needs to be explicit with either .* or *

What have you done so far? What specific problems are you having with your code?

If you must use the simple Euler method you need to write the equation in the following form:
p(i+1) = p(i) + dt*G*(pmax - p(i))*p(i);
where dt is your chosen timestep size, and i loops from 2 to N, where N is 20/dt. You would first set p(1) = 800.
