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 = 2×3

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

gsubtract({1 2; 3 4},{1 3; 5 2})
ans=2×2 cell
    {[ 0]}    {[-1]}
    {[-2]}    {[ 2]}

gsubtract({1 2 3 4},{10;20;30})
ans=3×4 cell
    {[ -9]}    {[ -8]}    {[ -7]}    {[ -6]}
    {[-19]}    {[-18]}    {[-17]}    {[-16]}
    {[-29]}    {[-28]}    {[-27]}    {[-26]}
