WebThe default behavior of circshift (A,K) where K is a scalar changed in R2016b. To preserve the behavior of R2016a and previous releases, use circshift (A,K,1). This syntax … WebDescription B = circshift (A,shiftsize) circularly shifts the values in the array, A, by shiftsize elements. shiftsize is a vector of integer scalars where the n -th element specifies the shift amount for the n -th dimension of array A. If an element in shiftsize is positive, the values of A are shifted down (or to the right).
