I think the gray does not mean "grayed out" there. Simply those icons are images and are designed with this lighter grey which lead to this confusion. Maybe you would like to file a bug so that we can keep track of this problem.

Maybe my understanding is incorrect. You just look at Nicolas' screenshot, mine is the same: the icons under "bordure" are all gray, while these options like "0.5in" and "Le tout ..." are black. I understand gray ones as disabled options.

Best wishes,

I do not think is really grayed out. Maybe the icon is not prominent enough. Can you pinpoint the problem? Sometime the color is different?

Thanks.

There seems to be a bug. I already found this option, grayed out (it is also gray in your screenshot), but it is clickable!

Hi,

I don't know if this is exactly what you're looking for, but when you insert a matrix, it is considered as a table, so you can create a separation using a table border.

When you have created the matrix of the correct size (with twice as many columns than lines, if I got it well), you have to select the vertical column of cells where you want your separation to be :

And then just click on the "border options" button next to the "cell" one in the top bar of Texmacs. Here, you can add a vertical border like this :

And you should have pretty clean separator between your two matrix.

Dear all,

I wonder whether I can add delimiters in matrices. For example, to
compute the inverse of a matrix A, it is customary to add a vertical
line to the matrix (A,I_n) as a delimiter (A|I_n). I wonder how to add
this vertical line "|" properly.

Best wishes,

Frank
