How can I integrate this ODE numerically?

  1. Apr 14, 2008 #1
    Hello to everybody I'm trying to integrate this ODE but I don't know how:

    f'''+a*f*f''=0 where a is a parameter.
    With the boundary conditions f(0)=0; f(-inf)=1; f(inf)=1.

    I had thought about using a shooting method but I don't know how to apply it with these boundary conditions. It would be nice if somebody could help me or give me a reference where I can find it( I have already looked for it in some books but I find nothing).

    Thank you.

    I'm sorry,there's a mistake in the boundary conditions. They are as follows:

    f(0)=0; f'(inf)=1; f'(-inf)=(a-1)/a; where a is a parameter.
