I have a computational project to do for quantum, and I am kind of tired of doing basic barriers, so I decided to try a quadratic barrier. Well, you get garbage. However, since I'm working with numerical approximations anyways, I figured I might try it, but I am not sure how to proceed. Here is what wolfram gives me:
http://www.wolframalpha.com/input/?i=-h^2/(2*m)*y''+++x^2*y+=+k*y
Note: k == Energy, I just used k because it changed E -> e.
If you scroll down and see the solution, it is in terms of the parabolic cylinder function D which is the solution to weber equations.

I am not really getting what to do with this.
I'm not sure on the notation used, and the link is no help.

Can someone give me advice on how to numerically approximate this function?
