Abstract
The paper describes a fast computational method for the numerical inversion of two-dimensional Laplace transforms (2D-NILT). The numerical procedure is basically that based on FFT algorithms (Brancik and Valsa, 1998), but it is improved significantly using an ε-algorithm to give precision to the result. Compared with the original method, the procedure under consideration enables the error to be decreased by a few orders. The method has been programmed and verified using the universal mathematical language Matlab
