    Computes the inverse FFT shift spectrum.


    c = ifft_shift(a)
    c = ifft_shift(a, b)
    Legacy name: ifftshift



    Vector or array of any dimension.


    Dimension for swapping. b is an integer. If you do not specify b, the function swaps each dimension sequentially.



    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. If a is a vector, c = ifft_shift(a) swaps each dimension sequentially. c is a vector or array of any dimension.
