MATLAB: Constructing a 1D using ifft

1d image

Hi there,
I get confused with all the website explaining how to construct an image from k-space using inverse fourier transform. I understand I need use abs(ifftshift(ifft(sig))) in order to produce a 2D image. Can someone please tell what I need to use in order to get a 1D image instead?
Best wishes

As long as sig is 1D, you should be getting 1D output.
    >> sig=1:5;  %1D signal
    >> abs(ifftshift(ifft(sig))) %1D output
    ans =
        0.5257    0.5257    0.8507    3.0000    0.8507
