SIP Toolbox

sip_fftshift - Swap arrays (used with fft)

Calling Sequence

Y = sip_fftshift(X)

Parameters

Description

sip_fftshift(X) swaps the left and right halves of X.

sip_fftshift is a substitute for mtlb_fftshift, a Scilab function which is in FRACLAB contribution. We provide it here, since its necessary for many image processing tasks.

Remarks

fftshift is now present in Scilab CVS. sip_fftshift is provided only for those versions of scilab that do not have fftshift.

There are optional arguments not documented, as well as other features of this function that we don't cover in this help page. Refer to the sourcecode (which is simple) for that.
