Running a pulse through an adjacency matrix

Hello! I'm relatively new to matlab and trying to complete a pulse process system. I have a 29x29 matrix and I'm trying to run a pulse through it. This is my code so far:

if true
  % code
%%Signed matrix

eye(29)+Mat+Mat^2

plot (vv) end My plot vv looks pretty decent, but some of the factors flatline and I'm not sure why. I need to get them to not flatline, but need the model to remain stable (not skyrocket into oblivion.)

I changed my matrix model to

end

but now I do not have oscillation...

I have also heard you can use Simulink to run a pulse through a matrix, but I don't know how...

Can anyone help me?

Thanks so much, Ash.
