WebSee this post from the other day and my comment there.. You don't need the length function. You don't even need the mod function. mod lets you do it in one line, but you could instead use an if statement that checks the sign of n. For example, if n is nonnegative then you could do: inputArray([end-n+1:end, 1:end-n]) WebYou can define macros in C/C++ to punt FFTSHIFT to CIRCSHIFT. A = rand (m, n); mm = floor (m / 2); nn = floor (n / 2); % All three of the following should provide zeros. circshift (A, [mm, nn]) - fftshift (A) circshift (A, [mm, 0]) - fftshift (A, 1) circshift (A, [ 0, nn]) - fftshift (A, 2) Similar equivalents can be found for IFFTSHIFT.
