It is a simple wrapper around the maxima inverse laplace function. > What I'd like is to get numerical results, so I thought there should > have been a way to obtain them, but I didn't find.

Not that I am aware of at the moment, but if it would be great if someone (for instance you) could implement it and send us a patch. - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
