Abstract
A Gaussian elimination form of inverse iteration within the complex coordinate approach is shown to produce a simple uniform method of finding both real bound state energies and complex resonant state energies for several problems which have been treated by a variety of methods in the literature. The energy shift method for expectation values is shown to be a useful diagnostic tool.
