In practice, it is more efficient to compute the discrete Fourier transform with the FFT than with the DFT matrix. The FFT also uses less memory. The two procedures give the same result. x = 1:256; y1 = fft(x); n = length(x); y2 = x*dftmtx(n); norm(y1-y2) ...
In this work, we mainly focus on parallel BCS scheme using complex-valued measurement matrix which can provide both high reconstruction quality and low computational complexity. The main contributions of our work are as follows. First, an image parallel BCS using DFT measurement matrix is proposed....
The first is the calculation of the dielectric functions within the density functional theory framework (DFT). The second is the calculation of the optical transmittance, absorbance and reflection of monolayer and multilayer thin films within the Abeles matrix theory. The output of this combination (...

The time-dependent density functional (TDDFT) equations may be written either for the Kohn-Sham orbitals in Hilbert space or for the single electron density matrix in Liouville space. A collective-oscillator, quasiparticle, representation of the density response of many-electron systems which ...
