ifftshift
Inverse zero-frequency shift
Description
X = ifftshift(
rearranges
a zero-frequency-shifted Fourier transform Y
)Y
back
to the original transform output. In other words, ifftshift
undoes
the result of fftshift
.
If
Y
is a vector, thenifftshift
swaps the left and right halves ofY
.If
Y
is a matrix, thenifftshift
swaps the first quadrant ofY
with the third, and the second quadrant with the fourth.If
Y
is a multidimensional array, thenifftshift
swaps half-spaces ofY
along each dimension.
