seemps.analysis.interpolation.fourier_interpolation(ψmps, space, old_sites, new_sites, strategy=<seemps.state.core.Strategy object>)[source]#

Fourier interpolation on an MPS.

Parameters:

ψmpsMPS: 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.
