AB - <p style="text-align: justify;">In the present paper a general technique is developed for construction of compact high-order finite difference schemes to approximate Schrödinger problems on nonuniform meshes.
Conservation of the finite difference schemes is investigated. The same technique is applied to
construct compact high-order approximations of the Robin and Szeftel type boundary conditions.
Results of computational experiments are presented.</p>
