The 2-D DFT is presented as two sets of 1-D DFTs. Examples of the 2-D DFT are given. The formal definitions of 2-D DFT and IDFT are presented. The computation of the 2-D DFT by the row–column method is described with examples. Finally, a comprehensive coverage of the properties of the 2-D DFT is presented with examples.

DFT and HF–DFT calculations of quadrupole coupling constants in molecules
Chemical Physics, 2000Abstract The efficacy of several DFT and HF–DFT methods for the calculation of 14 N quadrupole coupling constants in molecules has been investigated. Valence triple-zeta quality Pople and Dunning correlation consistent type bases were used.

Tensor Product DFT Codes vs Standard DFT Codes
IEEE Transactions on Computers, 2019We present a new class of linear error-correcting codes taking numerical data into codewords with numerical symbols. These codes can correct large random numerical errors added to codewords. The goal is for numerical data to be protected directly as numbers whether in storage or transmission.
