catelements

(To be removed) Concatenate neural network data elements

catelements 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

catelements(x1,x2,...,xn)
[x1; x2; ... xn]


Description

catelements(x1,x2,...,xn) takes any number of neural network data values, and merges them along the element dimension (i.e., the matrix row dimension).

If all arguments are matrices, this operation is the same as [x1; x2; ... xn].

If any argument is a cell array, then all non-cell array arguments are enclosed in cell arrays, and then the matrices in the same positions in each argument are concatenated.

Examples

This code concatenates the elements of two matrix data values.

x1 = [1 2 3; 4 7 4]
x2 = [5 8 2; 4 7 6; 2 9 1]
y = catelements(x1,x2)

This code concatenates the elements of two cell array data values.

x1 = {[1:3; 4:6] [7:9; 10:12]; [13:15] [16:18]}
x2 = {[2 1 3] [4 5 6]; [2 5 4] [9 7 5]}
y = catelements(x1,x2)
