    摘要: When a three-dimensional Fourier transform is performed on the data x (i, j, k), the Fourier transform is performed on each two-dimensional plane formed by a first dimension and a second dimension (two-dimensional array defined by i and j). Since data is stored in a continuous area in the direction in which index i expressing the first dimension continues, the transform of the first dimension is performed such that i can be continuous. When the Fourier transform of the second dimension expressed by j is performed, data is accessed such that i can continuously changes not by continuously changing j. The Fourier transform of the third dimension is performed with i continuously changed on each plane defined by i and k. Reversed bits are obtained by simultaneously exchanging the first dimensions and the second dimensions.
