Re: Help reproducing this matrix in TeXmacs

Hi Giovanni

Many thanks. Your instructions were very helpful. Now I have to figure out how to set the spacing and alignment. It is under cell size, right?

I think that the critical thing is to insert a subtable inside a
table. After you know how to do that: in the table Basile attached
to his message there are a few subtables. The table is so composed
(please Basile correct possible mistakes):

- overall, four cells: two rows of two cells each

- a subtable in the top right cell, made up of one row

- a subtable in the bottom left cell, made up of three rows, one
cell in each row

- a 3x3 subtable in the bottom right cell, enclosed in brackets

Once you have this design down, we can then get into the spacing
and alignment.

Thanks you! Unfortunately I did not figure out how you built the
table. Would you be so kind to write down the steps on how to do
it?

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.

Hi Eduardo,

a start might be inserting tables inside a
table, so that you may frame the rectangular
inner table with brackets and have a row
matrix and a column matrix on its sides. I
do not see, however, how to make sure that
the inner matrix stays aligned with the ones
on the sides.

Hi

I'm
trying to recreate the matrix shown in
the attached image using LaTeX and
also TeXmacs, but
I'm having some trouble — especially on
how to get the matrix notation.

Do you
have any tips or could you point me in
the right direction on how to do this?

Thanks
a lot in advance!

Best,

Ed
