Dear Aditya, Thank you for suggestion.
Here is my situation. ----- equation1 --------------------- ---- equation 2 --------------------- -----equation 3 ---- ] -----equation 4 ---- ] big rbrace for 3,4,5 and some text here -----equation 5 ---- ] -----equation 6 -------------------- According to your suggestion, we can use \startmatrix for 3,4,5, but how to put text? I googled and found a similar question in LaTeX, but the answer is to use tikz. How do you think? Thank you again. Best regards.
