Hi everyone, I am trying to use MATLAB to do Gillespie's algorithm for chemical reactions:

A + B --> C with rate f,

and C --> decay with rate d,

in which f = d = 1/s.

At time 0, A(0) = 20, B(0) = 10 and C(0) =10.

Could you please help me with this, probably using random number generator to represent probalities of each reactions?

Thank you all very much!
