shift.m

shift the elements of an array (of any dimension)

SHIFT (A, SHIFTSIZE, PADVAL) is an extension of circshift.m, allowing both integer and fractional shiftsize along all dimensions of A, and a padding different from circular. In the case of integer shiftsize, the algorithm of circshift.m is used which gives the same performance.
SHIFT is especially useful for the shift, including sub-pixel shift, of image data.

The padding methods are the same as in the MATLAB function padarray.m ('circular', 'replicate', 'symmetric'), as well as padding with numeric values (e. g. with 0) or with NaN. The screenshot shows an example of 'replicate' padding.
