[] { 1, 2, 3, 4, 5, 6 }; var newArray = new int? [oldArray.Length]; Array.Copy (oldArray, 1, newArray, 0, oldArray.Length - 1); // newArray is now { 2, 3, 4, 5, 6, null }

How to shift a matrix to the left without using circshift?

WebJan 3, 2024 · 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: The -1 and 2 in circshift denote the magnitude and the direction of shift respectively. You can use this for shifting up and down too. WebSay you were shifting it an amount n, you could use: A= [A (:,n+1:end) A (:,1:n)] Also, if you wanted to shift it the other way by 4, you could say: A= [A (:,end-3:end) A (:,1:end-4)] Or for n: A= [A (:,end-n+1:end) A (:,1:end-n)] tenwanksaday • 2 yr. ago.
