Detailed Description

Standalone C++ RAII wrapper for Fortran fitpack_parametric_curve.

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

Here is the call graph for this function:

◆ w()

fxArray< double > fpParametricCurve::w ( ) const

inline

Zero-copy fxArray view of component 'w'.

array_c_from_ptr builds the descriptor from the borrowed pointer and bounds, so the view aliases the Fortran storage directly — nothing is copied and writes through w()(i) land in the object.

Note: Only available when the Fortran-Arrays library is present and enabled (HAVE_FXARRAY).

Warning: The view is invalidated by any refit, assignment or destroy call on this object; re-read it rather than retaining it.

Here is the call graph for this function:

◆ w_vector()

std::vector< double > fpParametricCurve::w_vector ( ) const

inline

Deep copy of component 'w' as a std::vector.

Returns: An owning copy, empty when the component is unallocated.

Here is the call graph for this function:

◆ x()

fxArray< double > fpParametricCurve::x ( ) const

inline

Zero-copy fxArray view of component 'x'.

array_c_from_ptr builds the descriptor from the borrowed pointer and bounds, so the view aliases the Fortran storage directly — nothing is copied and writes through x()(i, j) land in the object.

Note: Only available when the Fortran-Arrays library is present and enabled (HAVE_FXARRAY).

Warning: The view is invalidated by any refit, assignment or destroy call on this object; re-read it rather than retaining it.

Here is the call graph for this function:

◆ x_shape()

std::array< int64_t, 2 > fpParametricCurve::x_shape ( ) const

inline

Extents of component 'x', leading dimension first.

Returns: All zeros when the component is unallocated.

Here is the call graph for this function:

◆ x_vector()

std::vector< double > fpParametricCurve::x_vector ( ) const

inline

Deep copy of component 'x' as a std::vector.

The rank-2 component is flattened COLUMN-MAJOR (Fortran order): element (i, j, ...) — zero-based — is at index i + j * extents[0] + ... Query the extents with x_shape().

Returns: An owning copy, empty when the component is unallocated.
