Extract data from dlarray

Syntax

Description

The extractdata function extracts the data from a dlarray object.

[Y](#mw%5F24b9b23b-a6da-4fb3-99da-41f6039f2b97) = extractdata([X](#mw%5Fb362e946-e132-4b79-902a-81a3f6d20cb6)) returns the data in the dlarray X. The output Y has the same data type as the underlying data in X.

example

Examples

collapse all

Create a logical dlarray with data format 'SS'.

rng default % For reproducibility dlX = dlarray(rand(4,3) > 0.5,'SS')

dlX = 4(S) × 3(S) logical dlarray

1 1 1 1 0 1 0 0 0 1 1 1

Extract the data from dlX.

y = 4×3 logical array

1 1 1 1 0 1 0 0 0 1 1 1

Input Arguments

collapse all

Input dlarray, specified as a dlarray object.

Example: X = dlarray(randn(50,3),'SC')

Output Arguments

collapse all

Data array, returned as a single, double, or logical array, or as agpuArray of one of these array types. The outputY has the same data type as the underlying data type inX.

Tips

• If X contains an implicit permutation because of formatting,Y has that permutation explicitly.
• The output Y has no tracing for the computation of derivatives. See Derivative Trace.

Usage notes and limitations:

Code generation does not support gpuArray data type.
