Hello everyone,
I am developing a new package https://github.com/AbdelazimHussien/MetaheuristicsAlgorithms.jl
Now, I am trying to display the equation in latex format but it doesn’t work. For example Engineering\_F3 show strange appearance
I checked JuMP and follow the same but I don’t know why it doesn’t appear
Any help

AFAIK docstrings with LaTeX should look like this:
```
@doc raw"""
This is an optimization algorithm.
Objective function:
```math
\xi + \eta^2
```
This is inline math: $\xi$ is positive.
"""
struct Algorithm
end
```
The main point is that LaTeX code should be surrounded by _triple backticks_, plus the first triple should be immediately followed by `math`. I used a raw string literal here to avoid escaping backslashes.
As a side note, many metaheuristics seem to be just particle swarm in disguise: [https://www.dei.unipd.it/~fisch/ricop/OR2/Metaheuristics-the%20metaphor%20exposed.pdf](https://www.dei.unipd.it/~fisch/ricop/OR2/Metaheuristics-the%20metaphor%20exposed.pdf).

U mean to put ```math before the matheamtical notation.
Right?

Yes, that is correct. Three backticks + `math`, then your math, then _three_ backticks again (your code currently has two). This is used for “display” math, like important equations.
Perhaps there are other ways, but this works for me.

As a concrete example from your latest commit, I’d write it like this:
```
@doc raw"""
Engineering_F3(x::Vector{Float64}) -> Float64
Welded Beam Design Optimization Problem.
Minimizes the cost of a welded beam subject to constraints on shear stress, normal stress, deflection, and geometric properties.
# Objective
```math
\vec{z} = [z_1, z_2, z_3, z_4] = [h, l, t, b] \\
\min_{\vec{z}} f(\vec{z}) = 1.10471 z_1^2 z_2 + 0.04811 z_3 z_4 (14 + z_2)
```
# Constraints
...
"""
function Engineering_F3(x)
5.0
end
```

You can find the complete documentation on how to use LaTeX at
> **[LaTeX Syntax · Documenter.jl](https://documenter.juliadocs.org/stable/man/latex/)**
>
> Documentation for Documenter.jl.
So besides block environments being
````julia
```math
[your math goes here]
```
````
if also documents that inline math should look like ```[your inline math goes here]```, i.e. with two backticks.
