Inversion of Laplace transforms has been accomplished by a numerical integration along appropriate paths in the complex plane. Two general procedures have been used. The simpler and more economical employs a simple path, such as a parabola, which bends to the left. Accuracy is maintained by monitoring the oscillation of the integrand. A second method employs a steepest descent contour.
