          This is more an extended comment on the answer by Sina Ahmadi. I will be happy to remove this if in that answer a few things get changed.





          1. tikzmark is a phantastic command that is part of the tikzmark library. I would like to argue that creating a new command with this name is not a good practice.

          2. The nodes right_end and down_left are not used. The lines are drawn as determined by the two hard-coded distances - ++ (1.7,0) and - ++ (0,-1.).




          documentclass{article}
          usepackage{amsmath}
          usepackage{tikz}

          [begin{bmatrix}

            You can really take them over, I do not want to post an answer here. I just want to avoid that tikzmark gets redefined.

            1. tikzmark is a phantastic command that is part of the tikzmark library. I would like to argue that creating a new command with this name is not a good practice.

            2. The nodes right_end and down_left are not used. The lines are drawn as determined by the two hard-coded distances - ++ (1.7,0) and - ++ (0,-1.).
