seemps.analysis.interpolation.finite_differences_interpolation_1D(vector: MPS, space: Space, dim: int = 0, order: Literal[1, 2, 3] = 1, strategy: Strategy = DEFAULT_STRATEGY)[source]#

Finite differences interpolation of dimension dim of an MPS representing a multidimensional function.

Parameters:
vectorMPS

MPS representing a multidimensional function.

spaceSpace

Space on which the function is defined.

dimint

Dimension to perform the interpolation.

orderint

Interpolation order, 1, 2 or 3 (defaults to 1).

strategyStrategy, optional

Truncation strategy, defaults to DEFAULT_STRATEGY.

Returns:
MPS

Interpolated MPS with one more site for the given dimension.
