c = ifft_shift(a)

c = ifft_shift(a, b)

Legacy Name: ifftshift


Computes the inverse FFT shift spectrum.



Name Description
a Specifies a vector or matrix.
b Specifies whether to perform swapping in the first or second dimension of a signal. b is an integer that accepts the following values.

1 Performs swapping in the first dimension.
2 Performs swapping in the second dimension.


Name Description
c Returns a shifted version of a. If a is a vector, ifft_shift(a) swaps the left and right parts of a. If a is a matrix, c = ifft_shift(a) swaps quadrants 1 and 3 and quadrants 2 and 4. c is a vector or matrix.


The following table lists the support characteristics of this function.
