Question

matlab help

Answer 1

here's the values
zombies2(0.005,0.0100,0.0900,0.0900,5,1)

and I will attach a txt for the code @Lyrae

Answer 2

I am trying to replicate figure 3 http://mysite.science.uottawa.ca/rsmith43/zombies.pdf

and hold on the code is coming... forgot to start my program

Answer 3

but my graph looks messed up !

Answer 4

the axis are fine, but the graph inside is a case of what just happened. And it's the infection being introduced into the basic model, so I had to use the S Z R model

Answer 5

@UsukiDoll: think the model should use αSR, instead of αSZ. So the equations on page 3 should read:

Z' = βSZ + ζR - αSR and
R' = δS + αSR - ζR

As with any problem, it'd be useful to clarify the equations which make up the model before proceeding to model the distribution empirically.

Answer 6

oh I'll try that and see what happens after I eat dinner

Answer 7

OK

Answer 8

Eulers method is iterative, try smaller time steps as well:

ie. dt = 0.1, 0.05, 0.01, 0.005, 0.001
zombies2(0.005,0.0100,0.0900,0.0900,5,dt)

until you find an acceptable converge rate (graph looks nice)
