catsignals

(To be removed) Concatenate neural network data signals

catsignals 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

catsignals(x1,x2,...,xn)
{x1; x2; ...; xn}


Description

catsignals(x1,x2,...,xn) takes any number of neural network data values, and merges them along the element dimension (i.e., the cell 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 the cell arrays are concatenated as [x1; x2; ...; xn].

Examples

This code concatenates the signals of two matrix data values.

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

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

x1 = {[1:3; 4:6] [7:9; 10:12]; [13:15] [16:18]}
x2 = {[2 1 3; 5 4 1] [4 5 6; 9 4 8]; [2 5 4] [9 7 5]}
y = catsignals(x1,x2)
