Description: Computation of energy eigenvalues of the anharmonic Coulombic potential with irregular singularities. The present contribution concerns the computation of energy eigenvalues of a perturbed anharmonic Coulombic potential with irregular singularities using a combination of the Sinc collocation method and the double exponential transformation. This method provides a highly efficient and accurate algorithm to compute the energy eigenvalues of one-dimensional time-independent Schrödinger equation. The numerical results obtained clearly illustrate the efficiency and accuracy of the proposed method.
