Detailed Description

Standalone C++ RAII wrapper for Fortran fitpack_constrained_curve.

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

◆ cp()

fxArray< double > fpConstrainedCurve::cp ( ) const

inline

Zero-copy fxArray view of component 'cp'.

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 cp()(i, j) land in the object.

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

◆ cp_vector()

std::vector< double > fpConstrainedCurve::cp_vector ( ) const

Deep copy of component 'cp' 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 cp_shape().

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

Here is the call graph for this function:

◆ cpp_type_name()

Here is the call graph for this function:

fxArray< double > fpConstrainedCurve::deriv_end ( ) const

inline

Zero-copy fxArray view of component 'deriv_end'.

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

std::vector< double > fpConstrainedCurve::deriv_end_vector ( ) const

◆ make_view()

static fpConstrainedCurve fpConstrainedCurve::make_view ( )

inlinestatic

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.

◆ mse()

double fpConstrainedCurve::mse ( ) const

Reimplemented from fpFitter.

		const std::vector< FP_REAL > &	u,
		const std::vector< FP_REAL > &	w,
		FP_REAL	smoothing = 1000.0,
		FP_SIZE	order = 3 )

inline

Fit a new curve through the points at parameter values u, with weights w.

FP_FLAG fpParametricCurve::new_fit	(	const std::vector< fpPoint< dim > > &	x,

inline

Fit a new curve through the points, choosing u by cumulative Euclidean distance.

◆ set_default_parameters()

void fpConstrainedCurve::set_default_parameters ( )

inlineoverridevirtual

Reimplemented from fpParametricCurve.

Here is the call graph for this function:

◆ xx()

fxArray< double > fpConstrainedCurve::xx ( ) const

inline

Zero-copy fxArray view of component 'xx'.

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 xx()(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:

◆ xx_shape()

std::array< int64_t, 2 > fpConstrainedCurve::xx_shape ( ) const

inline

Extents of component 'xx', leading dimension first.

Returns: All zeros when the component is unallocated.

Here is the call graph for this function:

◆ xx_vector()

std::vector< double > fpConstrainedCurve::xx_vector ( ) const

inline

Deep copy of component 'xx' 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 xx_shape().

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