✦ Synopsis


This paper describes a new method for numerical inversion of the Laplace transform based on a conformal mapping of the Bromwich path onto a unit circle. The inversion integral along the unit circle in a complex plane, is obtained numerically using the trapezoidal rule. Some numerical results of the present inversion technique are presented to discuss its characteristics, and an error estimate is also proposed for this type of inversion integral. Furthermore, the method is applied to solve a one-dimensional heat conduction problem.

Most methods for the numerical calculation of inverse Laplace transformations f(t) = L -1 [F(s)] have serious limitations concerning the class of functions F(s) that can be inverted or the achievable accuracy. The procedures described in the paper can be used to invert rational as well as irrational
