Evaluation at or near a pole.
A running error analysis for polynomial evaluation by nested multiplication using the recurrence suggested by Kahan (see Peters and Wilkinson (1971)) is used to detect whether you are attempting to evaluate the approximant at or near a pole.
8Parallelism and Performance
e02rbc is not threaded in any implementation.
The time taken is approximately proportional to .
This example first calls e02rac to calculate the Padé approximant to , and then uses e02rbc to evaluate the approximant at .
