What is High-Precision Eigenfunction Normalization about?
This document presents a method for computing normalization constants for wave functions of Schrodinger-type equations to very high precision. The key points are: 1) The trapezoidal rule provides the simplest and most accurate method for numerical integration, requiring a number of function evaluations that grows linearly with the desired precision. 2) For integrals over infinite ranges, the errors from a finite step size and finite integration range can both be estimated using the Fourier transform and
