Re: Help reproducing this matrix in TeXmacs

I agree that being able to label rows and column would be nice. Here is the best (not perfect) solution I have found so far.




I have forced the width of all cells to 3em.

If the different rows have different heights (say because some rows include fractions and some don’t), you could alternatively use <vphantom|> to force the height of label to match the height of the tallest box on the same row.

Basile.
