Wikipedia mentions two-point Padé approximant. I don't have access to the reference provided (Yoshiki Ueoka, Introduction to multipoints summation...).
I checked also chapter 8 (The N-Point Padé Approximants) in the George A. Baker's Esssentials of Padé Approximants, but could not translate the theory to a practical example myself.
Questions:
How to calculate two-point Padé approximants in general?
Could you provide an example? Let's say
e^x
at0
and1
of order3/3
?
