Abstract

We introduce an efficient and easily implemented numerical method for the inversion of Laplace transforms, using the analytic continuation of integrands of Bromwich's integrals. After deforming the Bromwich's contours so that it consists of the union of small circles around singular points, we evaluate the Bromwich's integrals by quadrature rules. We prove that the error bound of our method has spectral accuracy of type @?^N + eps/@?^P, 0
