How to write a match section

Inline:

• \( ... \)
• $ ... $ if enabled

Block:

• \[ ... \]
• $$ ... $$

Examples:

Inline

Inline \(tag{E=mc^2}\) math

<!-- Or -->

Inline $tag{E=mc^2}$ math

Block

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

<!-- Or -->

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

Options

You can toggle math by doing the following:

$Parsedown = new ParsedownMath([
    'math' => [
        'enabled' => true // Write true to enable the module
    ]
]);

Or if you only want inline or block you can use:

'math' => [
    ['inline'] => [
        'enabled' => false // false disable the module
    ],
    // Or
    ['block'] => [
        'enabled' => false
    ]
]

To enable single dollar sign for inline match:

$Parsedown = new ParsedownMath([
    'math' => [
        'matchSingleDollar' => true // default false
    ]
]);
