Detailed Description

Standalone C++ RAII wrapper for Fortran fitpack_polar.

This class provides automatic memory management (RAII) and a natural C++ API for the underlying Fortran fitpack_polar, without requiring the fortran-arrays library. Array arguments use std::vector<T> for standalone operation. Extends fpFitter (Fortran: extends(fitpack_fitter))
