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. WebMay 5, 2024 · You need to tell us how you want to use the data in the array.

I have a homework assignement that asks me to type code that will shift a single-row array of any size (i.e. a 1x9 array, or a 1x15 array, etc...) by n positions (n will be an inputed value). The function will be written as "circularShiftRight (inputArray, n)." WebY = 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. If K is a vector of integers, then each element of K indicates the shift amount in the corresponding dimension of A.
