Re: LaPlace Transforms in TI89 and HP48 compared by Perez-Franco
LaPlace92 and DiffEq92 are almost identical. In the beginning DiffEq92 was a
special version of LaPlace92, designed to solve differential equations, but
now LaPlace92 contain the same functions.
This debate, as I see, is must of all about ideology. HP users want to
propagate something ? It looks like that these tests was maid, so that it
would fit there needs. The conclusion was, shall we say subjective. I will
give an example. Maybe Erable is faster than LaPlace92, but Erable's
invLaPlace could not solve one out of four equations (25%). Erable can not
transform Heaviside and delta functions, LaPlace92/DiffEq92 can.
