seemps.analysis.cross.cross_interpolation(cross_strategy: CrossStrategy, black_box: BlackBox, initial_points: ndarray[tuple[Any, ...], dtype[_ScalarT]] | None = None) CrossResults[source]#

Computes the MPS representation of a black-box function using different the tensor cross-approximation (TCI) algorithm The black-box function can represent several different data structures. See black_box for usage examples.

Parameters:
cross_strategyCrossStrategy

A dataclass containing the parameters of the algorithm. See CrossStrategy.

black_boxBlackBox

The black box to approximate as a MPS.

initial_pointsMatrix | None, default=None

A collection of initial points used to initialize the algorithm. If None, an initial point at the origin is used.

Returns:
CrossResults

A dataclass containing the MPS representation of the black-box function, among other useful information.
