axiom

A Typst Math utility library providing notation shortcuts for recurrent operators absent for typst vanilla. Covers operators from various fields like probability or analysis.

Usage

#import "@preview/axiom:0.1.0": *

$ expec[X] = mu quad variance(X) = sigma^2 $
$ X tilde.op gauss(0, 1) $
$ argmax_(theta) f(theta) $
