Eigenvalue problem for a set of coupled Schrödinger like ODEs
Eigenvalue problem for a set of coupled Schrödinger like ODEs
The numerical solution of an eigenvalue problem for a set of ODEs may be non-trivial when high accuracy is needed and the interval of the independent variable extends to infinity. In that case, efficient asymptotics are needed at infinity to produce the initial conditions for numerical integration. Here such asymptotics …
