10.146. Split Data Array (By Tuple)

Group (Subgroup)

Data Manipulation (Memory/Management)

Description

This Filter splits a Data Array into several smaller arrays along a single tuple dimension. The user specifies how many tuples each output array should contain along that dimension; all other dimensions remain unchanged.

For example, given an array with tuple shape (4, 3):

{0} {1} {2}
{3} {4} {5}
{6} {7} {8}
{9} {10} {11}

with tuples for the output arrays set to 2 & 1 and split dimension set to 1 produces two new arrays with tuple shapes (4,2) and (4,1) respectively:

{0} {1}
{3} {4}
{6} {7}
{9} {10}
{2}
{5}
{8}
{11}

Output Container

The Output Container parameter controls where the resulting split arrays are placed:

  • New Data Group [0]: Creates a new DataGroup to hold the split arrays.

  • Existing Data Group [1]: Places the split arrays into an existing DataGroup selected by the user.

  • New Attribute Matrix [2]: Creates a new Attribute Matrix to hold the split arrays.

  • Existing Attribute Matrix [3]: Places the split arrays into an existing Attribute Matrix selected by the user.

An optional flag allows you to delete the original input array after splitting.

Looking to split by components instead?

See the Split Data Array (By Component) filter that separates each component into its own scalar array.

Tuple Counts

The per-output tuple counts are integers. The sum of all requested output counts along the split dimension must equal the input’s tuple count along that dimension.

Required Input Sources

  • Input Data Array – the array to split.

Description

Data Array

Array Selection

Allowed Types: int8, uint8, int16, uint16, int32, uint32, int64, uint64, float32, float64, boolean

The data array to split by tuples.

Output Container

Choices

Set the output container where the output split arrays will be stored.

Remove Original Array

Bool

Whether or not to remove the original data array after splitting

Split Dimension

Scalar Value

UInt64

The tuple shape dimension to split the arrays from the input data array.

Split Arrays: Split Dimension Counts

DynamicTable

How many tuples each output array should contain along the split dimension only.

• Enter one value per row; each row becomes a new split array. • The sum of all rows must equal the number of tuples in the input array’s split dimension.

Example: If the input array’s tuple shape is (100 × 200 × 300) and the filter is splitting along the first dimension (100), then Split Dimension Counts of 60 | 25 | 15 creates three output arrays whose tuple shapes are (60 × 200 × 300), (25 × 200 × 300), and (15 × 200 × 300) respectively. |
