How to shift an array without using circshift

WebShift array circularly collapse all in page Syntax Y = circshift (A,K) Y = circshift (A,K,dim) Description example Y = circshift (A,K) circularly shifts the elements in array A by K positions. If K is an integer, then circshift shifts along the first dimension of A whose size does not equal 1. WebFeb 25, 2016 · The circshift function is another solution: 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.
