Are there certain commands, or some mathematical trick I can use to recover the non-normalized solutions from NDEigensystem?
My equation of interest is of the form
I need the non-normalized functions and I'm not sure how to find them. I can't just insert $au(x)$ into my equation since the normalization constant would divide out.
Would my best option be to solve this equation again in NDSolve and explicitly insert the eigenvalue?
