In 2009, Munz et al.  have written a paper I have found pretty pedagogical. it dealt with the simulation of zombie infection among human population. I have therefore decided to re-write the Matlab code they propose in their paper, and to play a little with the different parameters. The present code is made of:
- one example file
- one zombies.m function that shows the basic model proposed by Munz et al.
- one erad.m function that is based on the "impulsive eradication" model.
There is no guarantees that the code I have written is reliable. If any doubt, please refers to the original one.
