Shifts the elements in an array by a specified number of shifts.

This node does not rotate the elements in the array. This node disposes of the elements of the input sequence shifted outside the range. You cannot recover those elements by shifting the array in the opposite direction.

Input array to shift.

Direction and number of shifts to apply to the input array. This node shifts the input array to the right if **number of shifts** is positive and to the left if **number of shifts** is negative.

The absolute value of **number of shifts** must be less than the number of elements in **input array**. If the absolute value of **number of shifts** is greater than or equal to the number of elements in **input array**, this node sets **shifted array** to 0 and returns an error.

**Default: **0

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

**Default: **No error

Output sequence.

Let the sequence *Y* represent the output sequence **shifted array**. Then the elements of *Y* are related to the elements of *X* by the following equation:

${Y}_{i}=\{\begin{array}{cc}{X}_{i-\mathrm{shifts}}& \mathrm{if}\text{\hspace{0.17em}}0\le i-\mathrm{shifts}<n\\ 0& \mathrm{elsewhere}\end{array}$

for *i* = 0, 1, ..., *n* - 1,

where *n* is the number of elements in **input array**.
