The discrete Fourier transform (DFT) and its efficient implementation using the fast Fourier transform (FFT) are used in a large number of applications36,37,38,39,40. Because the CZT is a generalization of the DFT and the ICZT is a generalization of the inverse DFT, the number of potentia...

constrain the prototype structures used as starting points in first-principles calculations such as DFT calculations which can be prohibitively expensive for high-throughput screening approaches. Moreover, by providing predicted symmetry and structure parameters, these predictions can help significantly ...

an external electric field is applied in a range from −1 to 1 V/Å. The DFT-calculated band gap at equilibrium is 1.97 eV, and we find most samples lie below this value under the applied strain and electric field (Fig.2b). Most notably, the vast majority of cases result in...
快速傅氏变换(fft)是离散傅氏变换(dft)的快速算法,它是根据离散傅氏变换的奇、偶、虚、实等特性,对离散傅立叶变换的算法进行改进获得的。它对傅氏变换的理论并没有新的发现,但是对于在计算机系统或者说数字系统中应用离散傅立叶变换,可以说是进了一大步。
