This directory documents where the tilewise Taylor approximation of the
complex-valued function w(z) comes from.

The code that generates lib/auto_taylor_wofz_coeffs.c and
lib/auto_taylor_wofz_tiles.c is the software project ttapp,
https://jugit.fz-juelich.de/mlz/app/ttapp, in particular
userManual/userManual.pdf; release 1.0 is archived at Zenodo,
https://doi.org/10.5281/zenodo.22277192. It can be used

- for verification of standard double-accuracy code,
- for generating reference values in tests, and
- for deriving coefficients in the tilewise Taylor approximation.

For background, see Wuttke, unpublished manuscript, available upon request.

Earlier implementations, in Python and then in C++, were developed
inside libcerf and have been retired.
