Constructor & Destructor Documentation

ScatteredTableND() [1/2]

vulcan::ScatteredTableND::ScatteredTableND ( const janus::NumericMatrix & points, const janus::NumericVector & values, int grid_resolution = 20, RBFKernel kernel = RBFKernel::ThinPlateSpline, double epsilon = 1.0, janus::InterpolationMethod method = janus::InterpolationMethod::Linear )

inline

Construct N-D scattered interpolation table.

Parameters

points	Data locations, shape (n_points, n_dims)
values	Function values at each point (length n_points)
grid_resolution	Points per dimension for resampling grid
kernel	RBF kernel type (default: ThinPlateSpline)
epsilon	Shape parameter for Multiquadric/Gaussian kernels
method	Gridded interpolation method for final queries

Exceptions

janus::InterpolationError

if inputs are invalid

Member Function Documentation

dims()

int vulcan::ScatteredTableND::dims ( ) const

inline

Get number of input dimensions.

Examples

/home/runner/work/vulcan/vulcan/include/vulcan/core/TableInterpolator.hpp.

operator()()

template<janus::JanusScalar Scalar>

Scalar vulcan::ScatteredTableND::operator() ( const janus::JanusVector< Scalar > & x ) const

inline

Query table at a single N-D point.

Template Parameters

Scalar

Scalar type (double or janus::SymbolicScalar)

Parameters

x	Query point (size must match dims())

Returns

Interpolated value

Examples

/home/runner/work/vulcan/vulcan/include/vulcan/core/TableInterpolator.hpp.

reconstruction_error()

double vulcan::ScatteredTableND::reconstruction_error ( ) const

inline
