gslevu
This library exports a pair of functions of the form
library('gslevu','accel') library('gslevu','utrunc') |
that take a list of real numbers x to a pair of real numbers
(s,e)
.
The idea is that x represents the first few terms of an infinite series whose sum converges, but only very slowly. The functions extrapolate an estimate of the infinite summation by the Levin u-transform as documented in the GNU Scientific Library reference manual.
For well behaved series, considerably fewer terms are needed for an accurate estimate than a direct summation would require.
