Solve the first-order ode with power n (inhomogeneous)

Hi All,

I'm trying to solve the following equation numerically:

y'/G+A*y^n=r0

where G, A, r0, and power n are constant, and y is a function of t with boundary conditions:

y(0)=y0+dy0, y(t->inf)=y0,

where y0=(r0/A)^(1/n) and dy0 is a constant.

Could I solve this equation by ode45 or ode23?

Thanks,

CH
