seemps.analysis.interpolation.fourier_interpolation(tensor: MPS, space: Space, old_sites: list, new_sites: list, strategy: Strategy = DEFAULT_STRATEGY)

Fourier interpolation on an MPS.

Parameters:

tensorMPS

Discretized multidimensional function MPS.

space: Space

Space object of the defined ψmps.

old_siteslist[int]

List of integers with the original number of sites for each dimension.

new_siteslist[int]

List of integers with the new number of sites for each dimension.

strategyStrategy, optional

Truncation strategy, defaults to DEFAULT_STRATEGY.

Returns:

MPS

Interpolated multidimensional function MPS.
