I have a function is Laplace Domain which is very complicated and I need to invert it numerically into time domain as analytical inversion takes a lot of time. The problem is that neither the Talbot method, nor the GWR method are giving meaningful results. I used the subroutines given in the wolfram pages themselves for the inversion, but they are not working. Talbot gives diverging answers for short times and GWR does not even run. Does anyone know any way out?
