Hello, I would like to create two vectors or matrices, such that the rows of each vector/matrix line up horizontally. For example, consider the following
$ vec(f_a, f_b, f_c) = vec(a, b, c) $

I would instead like the right vector to have vertical padding in each cell, such that I can draw parallel lines from $f_a$ to $a$, $f_b$ to $b$, and so on.
I tried to use the gap parameter, but this yields the following results:
#set math.vec(gap: 2em)
$ vec(f_a, f_b, f_c) = vec(a, b, c) $

I can get closer using grid, but it requires manual tuning and the braces still differ.
$ vec(#grid(columns: 1, gutter: 5pt, $ f_a $, $ f_b $, $ f_c $)) = vec(#grid(columns: 1, gutter: 10pt, $ a $, $ b $, $ c $)) $
As a new user, I can only add two images so you will need to imagine the results.
