Web如果您指定 K 为整数,但不指定 dim,则 circshift 将沿其大小不等于 1 的第一个维度平移。 正 K 向维度末尾平移,负 K 向开头平移。. 如果将 K 指定为整数向量,则 K 中的第 N 个元素指定 A 中第 N 个维度的平移量。 如果 K 中的第 N 个元素为正值,则 A 的值将向第 N 个维度 … WebY = fftshift (X) rearranges a Fourier transform X by shifting the zero-frequency component to the center of the array. If X is a vector, then fftshift swaps the left and right halves of X. If X is a matrix, then fftshift swaps the first quadrant of X with the third, and the second quadrant with the fourth. If X is a multidimensional array, then ... how big are among us characters
