Homework Statement
Find eigenvalues and eigenvectors of a perturbed harmonic oscillator (H=H0+lambda*q4 numerically using different numerical methods and plot perturbed eigenfunctions. I wrote a code in c++ which returns a row of eigenvalues of the perturbed matrix H and a matrix of corresponding eigenvectors. I know how to plot eigenfunctions of a non-perturbed oscillator in Mathematica. But here it ends. It's been a while since I had a course in classical mechanics and I can't remember (or find it on web, Wikipedia was also useless) how do you actually find eigenfunctions for eigenvalues and eigenvectors. Can please anyone explain to me how to do that?
Thank you in advance
