a problem with Integration

I have model to be solved. this model has 2 equations and 2 unknowns including a PDE and an ODE. sothing like this:
S + tav * d(S,t) = Eta , Eta=ETA(x,t) & S=s(x,t)
d(S,t) = d^2(phi)/dx^2
and
phi = -int{f(S)*g(S)dS_from_0_to_Eta}
I do not know how to introduce this integration to my model. Is the int(f,0,Eta) function (like Matlab) working? can anyone help?
kind regards,
Mohammad
