http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/circshift.html 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).

WebJan 4, 2024 · 3. You can probably use circshift and set the shifted space to zero manually. For example, if you had to shift a matrix left and have zeroes padded to the right, you'd do something like: shifted_mat = circshift (mat, -1, 2); shifted_mat (:, end) = 0; The -1 and 2 in circshift denote the magnitude and the direction of shift respectively.
