WebAug 6, 2015 · FSHIFT shifts the elements in a vector by a given number of elements, as CIRCSHIFT does. However, a non-integer shift value can be used, in which case the elements are shifted along the perfect (sinc-based) interpolation of the periodisation of the vector. For integer shift values, FSHIFT is equivalent to CIRCSHIFT to machine precision.
