To plot a logistical population growth model with multiple value outputs in Matlab, you can follow these steps:
Define the variables:
r
= the intrinsic growth rate (dN/dt) of the populationK
= the carrying capacity of the populationN0
= the initial population sizet
= the time frame for the population growthWrite the logistic function formula:
main.m37 chars2 lines
Use the plot()
function to plot the population size N
as a function of time t
. You can also include multiple output curves by specifying different input values for the variables r
, K
and N0
.
Here's an example code snippet:
main.m528 chars18 lines
This will produce a plot with two curves representing the growth of two populations with different intrinsic growth rates (r1
and r2
) but same carrying capacity and initial population size. You can adjust the variables as needed to explore different scenarios.
