I am trying to numerically simulate the population growth model dn/dt=rn(n/u-1)(1-n/k) If u=1000 and k = 2000, plot solutions for 5 different values of N(0) < 3000. I know how to plot I am just not sure how I am supposed to go about numerically simulating the model.

Your equations looks like ODE (ordinary differenetila equation)
You need to plot(t,n)?

Hello Clementine,
As mentioned above, if you are dealing with ODE refer to following documentation of 'ode45' to solve the ODE:
https://www.mathworks.com/matlabcentral/answers/506531-numerical-simulation-of-population-growth
In your case, you can solve the ODE for five different initial conditions and get the solution.
Hope, this will help you
