Circshift in matlab

WebSep 20, 2016 · Shifting that huge 2D array, M with circshift would surely be expensive. So, one trick could be to shift around the 1D array v instead in the other direction and keep M as it is. So, we need just one edit to replace : circshift (M, [0 ii])*v with M*circshift (v,-ii). The runtimes for M as (2500 x 2500) sized array with the original and proposed ...
