Deal all, output = padarray(input,[ x y],'replicate') function does not work in the minus domain x and y. Especially, the output size compared to input (e.g., image) naturally changed, but I would like to keep same size with input matrix. On the other hand, circshift(input,[ x y]) function work well in the minus domain x and y.
So, I wanna to use the circshift function in the minus domain likewise 'replicate' mode of padarray function. or zero-padding using cirshift function. Do you have any good idea??
Many thanks.

Can you post a small example with data? I'm not sure if the wanted procedure is clear to me after reading the text.
