This repository tackle the problem of approximating a multivariate function defined on a general domain in high-dimensions from sample points. We solve a regression problem via weighted-least-squares.

COBRA methods are widely used for genome-scale modeling of metabolic networks in both prokaryotes and eukaryotes. COBRApy is a constraint-based modeling package that is designed to accommodate the ...

Point spread function (PSF), which is the intensity distribution of optical system impulse response and usually acquired by imaging a single pinhole in experiment, can characterize the quality of ...

Boson sampling is a computational problem, which is commonly believed to be a representative paradigm for attaining the milestone of quantum advantage. So far, massive efforts have been made to the ...

Abstract: In digital signal processing, a method for obtaining the output signal by convoluting sampled-values as an input signal with the sampling functions which are typical impulse responses is ...

The Wigner phase-space formulation for systems possessing SU(1,1) symmetry has been defined by Seyfarth et al. [Quantum 4, 317 (2020)] tackling the difficulty in defining a suitable operational ...

Abstract: The linear canonical transform (LCT) has been shown to be useful and powerful in signal processing, optics, etc. Many results of this transform are already known, including sampling theory.
