Detailed Description

Standalone C++ RAII wrapper for Fortran fitpack_convex_curve.

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

Construct an empty (non-owning) wrapper, for use as a view target.

The returned object has a null handle (cptr==nullptr, is_pointer==false) and does NOT allocate a Fortran object. Intended as a fill target for member-view accessors emitted on parent types — the parent populates the handle with c_loc() into its own storage and sets is_pointer=true.

set_convexity

Here is the call graph for this function:

◆ sx()

fxArray< double > fpConvexCurve::sx ( ) const

inline

Zero-copy fxArray view of component 'sx'.

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 sx()(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:

◆ sx_vector()

std::vector< double > fpConvexCurve::sx_vector ( ) const

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

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

◆ v()

fxArray< double > fpConvexCurve::v ( ) const

inline

Zero-copy fxArray view of component 'v'.

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 v()(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.

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