I think the dirac delta is very widespread both in mechanics and in electronics (because of frequency domain representation of sine function as a tone - dirac(w) - centered at the sine frequency), although I am not sure what about its derivatives. I know this issue has been taken into account in SymPy in a way pretty similar to Mathematica's approach.
I frequently use Laplace transform, instead of Fourier (where delta is very common), so I can't tell so much from my experience with the MatLab symbolic package (which used to rely on maple as well, before the MuPad acquisition). Thanks for showing interest, this is very important :) Maurizio > The derivative of the dirac delta shows up in solid mechanics, is that > defined at all? > > I have major problems with Maple because its integration of Heaviside > functions is often wrong. > > Cheers, > > Tim. > > --- > Tim Lahey > PhD Candidate, Systems Design Engineering > University of Waterloohttp://www.linkedin.com/in/timlahey --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
