The numerical solving of certain singular boundary value problems of quantum mechanics and quantum field theory by using a common computational approach, which is briefly exposed, is considered. One simple problem, which arose in the theory of composite hadrons, is investigated in detail. Using this problem as a typical example one formulates a method of analytic continuation of the numerical solution defined on the real axis into the whole complex plane.
