摘要
首先将Laplace变换转化成Hausdorff矩问题,然后基于矩问题的稳定化算法,由像函数F(s)的N+1个数据F(1),F(2),…,F(N+1)获得Laplace逆变换的数值解及其稳定性估计。数值模拟显示了算法是有效的和实用的。
Laplace transforms are converted to Hausdorff moment problems. Then based on the stability algorithm of Hausdorff moment problems, the numerical solution of inversion Laplace transforms and its stability estimation are obtained by the measure data F( 1 ),F(2),…,F(N+1 )of the image function F(s ). Numerical simulations show the efficiency and practicality of the algorithm.
