This page explains how to use the array_shift_left function in APL.
array_shift_left
function in APL rotates the elements of an array to the left by a specified number of positions. If the shift exceeds the array length, it wraps around and continues from the beginning. This function is useful when you need to realign or reorder elements for pattern analysis, comparisons, or other array transformations.
For example, you can use array_shift_left
to:
Splunk SPL users
array_shift_left
, but you can achieve similar results using custom code or by manipulating arrays manually. In APL, array_shift_left
simplifies this operation by providing a built-in, efficient implementation.ANSI SQL users
array_shift_left
. Typically, you would use procedural SQL to write custom logic for this transformation. In APL, the array_shift_left
function provides an elegant, concise solution.Parameter | Type | Description |
---|---|---|
array | Array | The array to shift. |
shift_amount | Integer | The number of positions to shift elements to the left. |
shift_amount
. The function wraps the excess elements to the start of the array.
