How to render LaTeX math expressions

[aagudeloz]

I’m using Pythonista Lab on iOS. How can I format and display mathematical expressions, like subscripts or LaTeX-style equations? For example, $i_2$ is not rendered properly.

As mentioned in the release notes, this isn't supported (yet).

I’d really appreciate your help. Could someone point me to where I can find the release notes or changelog for Pythonista Lab? I’d like to better understand what’s currently supported, especially regarding math rendering and notebook features.

Thanks in advance!

The release notes are currently at the bottom of the start screen (when no file is open).

Hi Ole,
Is Pythonista Lab released on App Store yet? TestFlight expired some time ago.

I was trying to find out if that is possible, then I figured out an indirect way to do it. Not perfect but works.

import sympy as sp

def math_show(latex):
	import matplotlib.pyplot as plt
	
	fig, ax = plt.subplots(figsize=(6, 1))
	
	ax.text(
	    0.5,
	    0.5,
	    f"${latex}$",
	    fontsize=24,
	    ha='center',
	    va='center'
	)	
	ax.axis('off')	
	plt.show()
	
x, n = sp.symbols('x n')
math_show(sp.latex(sp.limit(1-((n-1)/n)**n, n, sp.oo)))
