Input Parameters

array—An array.

dimension—An integer (³0) designating the shift dimension.

shift_amount—An integer specifying the shift amount.

Returned Value

result—An array of the same dimensions as array. The result is obtained from the input array by a shift of shift_amount elements along dimension dimension. The shift is not cyclic; elements behind the shift are unaltered.

Keywords

y—If set, the shift is cyclic.
