produces the following picture: enter image description here

which horizontally align the matrices setting the captions in the same row to be aligned. I would like to align matrices of the same row to have the S= at the same height (aligned S's in two rows).

  • This question has been edited for the sake of clarity – user1993416 Jun 20 '18 at 15:01
  • @Zarko I have also added all packages I use in my document. Package subcaption of proposed solution results in errors when compiling the whole document. – user1993416 Jun 20 '18 at 15:07
  • of course, if you use subcaption, you should remove subfigure (which is obsolete). – Zarko Jun 20 '18 at 16:20

  • new content of question, so new answer ...
  • like this (i still don't know, what you like to obtain, now i guess that you like to align subcaptions as well S in equations):

is this what you looking for?

note: i don't understand why you enclose matrices in tikz nodes. i use simple display math environment for them.

edit (1): in case, that you like to top align first two matrices than at second pair remove option [t] or add option [b]:

  • @Zarko thank you. With tikzpicture the captions look better because matrices are figures. In the solution the first and the second row are justified up. I was looking to justify up only the first row and leave the second row the same, with figures and captions (c) and (d) at the same level. – user1993416 Jun 19 '18 at 20:47
  • @marmot Thanks. Can I change something in my code to raise just the matrix (b)? – user1993416 Jun 19 '18 at 21:04
  • @user1993416, sory, i don't understand you. can you illustrate this with some sketch. regarding tikz node, i don't see any benefits in its use. if you like the top alignment of matrices only at first two subfigures, remove [t] at third in forth subfigure. – Zarko Jun 19 '18 at 21:13
  • @marmot thanks. I have made an edit of the initial question. It seems I can not use the subcaption package in my paper. – user1993416 Jun 20 '18 at 7:08
  • @user1993416, please let me know with which packages you find incompatibility of subcaption with other packages. so far i didn't met any. also is not nice to change question and with this nullified received answer. i suggest to close your question as "not clear what you asking for". – Zarko Jun 20 '18 at 10:49
