Quartz uses Katex by default to typeset both inline and block math expressions at build time.

Syntax

Block Math

Block math can be rendered by delimiting math expression with $$.

$$
f(x) = \int_{-\infty}^\infty
    f\hat(\xi),e^{2 \pi i \xi x}
    \,d\xi
$$

f(x) = \int_{-\infty}^\infty f\hat(\xi),e^{2 \pi i \xi x} ,d\xi

\begin{aligned} a &= b + c \ &= e + f \ \end{aligned}

\begin{bmatrix} 1 & 2 & 3 \ a & b & c \end{bmatrix}

[!warn] Due to limitations in the underlying parsing library, block math in Quartz requires the $$ delimiters to be on newlines like above.

Inline Math

Similarly, inline math can be rendered by delimiting math expression with a single $. For example, $e^{i\pi} = -1$ produces e^{i\pi} = -1

Escaping symbols

There will be cases where you may have more than one $ in a paragraph at once which may accidentally trigger MathJax/Katex.

To get around this, you can escape the dollar sign by doing \$ instead.

For example:

• Incorrect: I have $1 and you have $2 produces I have $1 and you have $2
• Correct: I have \$1 and you have \$2 produces I have $1 and you have $2

Customization

Latex parsing is a functionality of the plugins/Latex plugin. See the plugin page for customization options.
