Web: y = circshift (x, n, dim) Circularly shift the values of the array x . n must be a vector of integers no longer than the number of dimensions in x. The values of n can be either positive or negative, which determines the direction in which the values of x are shifted. WebB = shiftdim (A,n) shifts the dimensions of an array A by n positions. shiftdim shifts the dimensions to the left when n is a positive integer and to the right when n is a negative integer. For example, if A is a 2-by-3-by-4 array, then shiftdim (A,2) returns a …
