Reconstruction of Exponential Sums from Fourier Data via Rational Approximation
(2022-07-08)We develop the new ESPIRA Algorithm to reconstruct exponential sums from discrete sample values, using the discrete Fourier transform of the given sample vector. We exploit the structure of the DFT values of samples from ...
