Another addition to the Pade Approximant function that would be very
useful would be the generalized Pade Approximant: these are Pade
Approximants that are based on more than one expansion point. I coded
this up many years ago for some work in Radar propagation analysis
(never published but I really should have...):

more stuff on Radar is here...  which I really should do something
commercial with sometime....
