How to use matlab to solve differential equations with variables?

Hey all, I'm trying to use matlab to give me the fixed points for a system of differential equations written in all variables. Here's my specific problem I'm trying to do:

dI/dt = s + p*I*T/(a+T) - c1*I*T - d1*I

dT/dt = r1*T(1-b1*T) - c2*I*T - c3*T*N

dN/dt = r2*N(1-b2*N) - c4*T*N

any advice is of much help. Thanks!
