Hi jackmell, Thanks a lot! Your suggestion is very valuable to me. I adjust my DE to \left(y')^2=a+cy^2+dy^3 with the boundary of \left y(\infty)=0 and the simplified equation is \left(y')^2=cy^2+dy^3 By subtitute \left t=\sqrt{c+dy} I finally get \left \frac{adt}{t^2-b}=dx And its...

Thank your reply. The attached picture is a given method for solving this kind equation, but it is uncompleted. For I am not good at math and I can't get a good solution from matlab, could anyone help me on this? Best wishes! elfine

Dear Everyone, I am working on a physics problem of exciton diffusion involved in organic optoelectronics. It is in the form of y''+a*y+b*y^2=0. Is there a general solution to this equation? Thanks! elfine
