摘要：

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 [1], however, it was improved significantly using an E-algorithm to give a precision to the result. Comparing with the original method [1] the procedure under consideration enables to decrease an error by a few orders. The method has been programmed and verified using universal mathematical language Matlab, Obtained results show that the proposed algorithm can be both very fast and accurate enough.
