I already have this matrix:



[
left[
begin{array}{ccc}
1 & 0 & 0 \
0 & 1 & 0 \
0 & 0 & 1 \
end{array}
right]
]


But I would like to annotate it, i.e. add some description below it (everything in red).. How can I do that please?

          You have the underbracket command from mathtools. I simplified your code using the bmatrix environment from amsmath (which is loaded by mathtools):



          documentclass{article}
          usepackage{mathtools}

          begin{document}

          [
          underbracket[0.6pt]{begin{bmatrix}
          1 & 0 & 0 \
          0 & 1 & 0 \
          0 & 0 & 1
          end{bmatrix}}_text{some text here}
          ]

          end{document}

            mathtools has underbracket (see here: overbrace and underbrace with square bracket).



            documentclass{article}
            usepackage{xcolor}
            usepackage{mathtools}

            begin{document}
            [
            textcolor{red}{underbracket{textcolor{black}{left[
            begin{array}{ccc}
            1 & 0 & 0 \
            0 & 1 & 0 \
            0 & 0 & 1 \
            end{array}
            right]}}_{text{some text here}}}
            ]
            end{document}
