seemps.analysis.factories.mps_sum_of_exponentials(interval: QuantizedInterval | IntervalTuple, k: Sequence[float | complex], weights: Sequence[float | complex] | complex | float | int = 1.0) → MPS[source]#

Create an MPS representing a sum of exponentials evaluated over a half-open interval.

Creates an MPS representation of a function

\[f(x) = \sum_n w_n exp(-i k_n x)\]

Parameters:

interval: QuantizedInterval | IntervalTuple: The interval over which the function is defined.
kSequence[Weight]: Sequence of exponents in the function.
weightsSequence[Weight] | Weight: Sequence of weights, or a uniform weight for all exponentials (default is 1.0).

Returns:

MPS: The MPS encoding of the function.
