getelements

(To be removed) Get neural network data elements

getelements will be removed in a future release. For more information, see Transition Legacy Neural Network Code to dlnetwork Workflows.

For advice on updating your code, see Version History.

Syntax

getelements(x,ind)


Description

getelements(x,ind) returns the elements of neural network data x indicated by the indices ind. The neural network data may be in matrix or cell array form.

If x is a matrix, the result is the ind rows of x.

If x is a cell array, the result is a cell array with as many columns as x, whose elements (1,i) are matrices containing the ind rows of [x{:,i}].

Examples

This code gets elements 1 and 3 from matrix data:

x = [1 2 3; 4 7 4]
y = getelements(x,[1 3])

This code gets elements 1 and 3 from cell array data:

x = {[1:3; 4:6] [7:9; 10:12]; [13:15] [16:18]}
y = getelements(x,[1 3])

Version History

Introduced in R2010b
