    Hi friends,

    I have been trying to solve the ode of second degree below:


    i is the complex i, a and b are constants

    i ended up with the summation of bessel functions of first end second kind. Then I checked with matlab ode solver it gives no explicit solution. please help me.

    Thank you so much!

    First, your problem is not well written. 1/a*z+b could be interpreted as (1/a)z+ b, or as [1/(az)]+ b, or as 1/(az+ b).

    sorry about that

    it is:


    i is complex i not a symbol

    i am also looking for a solution for this wrt z:


    thank you!
