Hello,  
I have a model based on a set of ordinary differential equations, wrapped in a function. Is it possible to convert it into latex?

For instance,

```julia
function X!(du, u, p, t)
    A = p[:a] # parameter a
    B = p[:b] # parameter b

    du[1] = (A*u[1]*(1/B)
    du[2] = (B*u[2]*(1/A)
end

```

Thank you

If you can define it using [ParameterizedFunctions’ @ode\_def](https://diffeq.sciml.ai/stable/analysis/parameterized_functions/), then the Latexify package can convert that into nice-looking LaTeX. See [the Readme section](https://github.com/korsbo/Latexify.jl#use-with-differentialequationsjl) and [the docs page](https://korsbo.github.io/Latexify.jl/stable/tutorials/parameterizedfunctions/).

And if you want to roll your own, you can do

```julia
using Latexify 
@latexify du = [A/B B/A]*u

```

or

```julia
@latexify [du_1, du_2] = [A*u_1/B, B*u_2/A]

```
