Member of the transforms class.

Syntax

c = ifftshift(a)

c = ifftshift(a, b)

Description

Computes the inverse FFT shift spectrum.

Examples

Inputs

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.

Outputs

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

Examples

A = [1, 2, 3, 4; 4, 3, 2, 1]
C = ifftshift(A)
