Hi all,
As shown in the screen shot, I would like to reference variables inside a LaTeX matrix. Here is the code I am using. Any help would be greatly appreciated.
Perhaps another approach could parse a string of the code into markdown. This is what is described here in R.
How can I convert
my_markdown = "\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}"
into markdown? I tried various solutions such as
md"""
$(my_markdown)
"""
without success.
Hi Christopher. There are at least two ways to do this, one awkward way using the Julia standard library, and another one with the small LaTeXStrings package.
Standard library way, but involves lots of escaping on \:
import Markdown: MD, LaTeX
MD(LaTeX("\\mathbf{B} = \\begin{bmatrix} $(a) & $(b) \\\\ $(c) & $(d) \\end{bmatrix}"))
Using LaTeXStrings, with the interpolation done with %$ instead of just $:
using LaTeXStrings
L"""
\mathbf{B} = \begin{bmatrix} %$(a) & %$(b) \\ %$(c) & %$(d) \end{bmatrix}
"""
You can copy from below and paste into a .jl file to get a Pluto noteboook:

Thank you for your help. Indeed, the solution using LaTeXStrings is very nice and simple. Thanks again!
