kronrod

Fortran program for generating Gauss-Kronrod coefficients.

Uses the MPFUN2020 arbitrary precision Fortran library.

The purpose of this is to use it for the new modernized QUADPACK library.

Building

A Fortran Package Manager manifest file is included, so that the application can be compiled and run with FPM. For example:

fpm run --profile release
