Hello,

I am using mathematica 9 and having some problems with a particular expression, but when I tried it on mathematica 8 it worked perfectly. My expression is:

NDSolve[{D[T[n,z],n]+i 2 D[T[n,z],{z,2}]+z^2 T[n,z]==0,T[0,z]==1,Derivative[0,1][T][n,5]==0,Derivative[0,1][T][n,0]==0},T,{n,0,5},{z,0,5}]

where i is the imaginary number, and on both I had a new window to work on, with nothing having been done previously on it.

Mathematica 8 gave me this:
{{T-> InterpolatingFunction[{{0.,5.},{0.,5.}},<>]}}

and mathematica 9 gave me this:
NDSolve::ndnum : Encountered non-numerical value for a derivative at n==0.`.>>

Does anyone know what is going on here? I cannot use mathematica 8, as I do not have continual access to that machine.

Thank you for your help.
