gsubtract

R2026b

(To be removed) Generalized subtraction

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

Syntax

gsubtract(a,b)


Description

gsubtract(a,b) takes two matrices or cell arrays, and subtracts them in an element-wise manner.

Examples

Subtract Matrix and Cell Array Values

This example shows how to subtract matrix and cell array values.

gsubtract([1 2 3; 4 5 6],[10;20])

ans =

    -9    -8    -7
   -16   -15   -14

gsubtract({1 2; 3 4},{1 3; 5 2})

ans =

  2x2 cell array

    {[ 0]}    {[-1]}
    {[-2]}    {[ 2]}

gsubtract({1 2 3 4},{10;20;30})

ans =

  3x4 cell array

    {[ -9]}    {[ -8]}    {[ -7]}    {[ -6]}
    {[-19]}    {[-18]}    {[-17]}    {[-16]}
    {[-29]}    {[-28]}    {[-27]}    {[-26]}

R2026a: gsubtract will be removed

gsubtract will be removed in a future release.

To learn more about supported mathematical and deep learning operations and layers, see these examples and topics:

To perform element wise subtraction on numeric arrays, use the minus (-) function. For cell arrays, loop over the elements of the array and use the minus (-) function.
