Finding Maximum Arrival Rate in Matlab using Graph Plot

I have created the code for my matrix in queuing network(more focused on Open Queuing Network). However I am new to Simulink and I need some help in plotting and creating a graph(not sure if I need to use Simulink).

Here is my code:

N=6
M_sparse=sprand(N,N+1,0.5)
M=full(M_sparse)
M(1:1+size(M,1):end)=0
R=M(1:end,1:end-1)
determinant=det(eye(N)-R)
Q=inv(eye(N)-R)
gamma=randi([0 1],1,N)
lambda=gamma*Q

What I want to do is get time into the picture of arrival rates, to find the maximum arrival rate and how it behaves.
