# boldsymbol

The boldsymbol extension defines the `\boldsymbol` LaTeX macro that produces a bold version of its argument, provided bold versions of the required characters are available.

This extension is loaded automatically when the autoload extension is used. To load the boldsymbol extension explicitly (when using `input/tex-base` for example), add `'[tex]/boldsymbol'` to the `load` array of the `loader` block of your MathJax configuration, and add `'boldsymbol'` to the `packages` array of the `tex` block.

    window.MathJax = {
      loader: {load: ['[tex]/boldsymbol']},
      tex: {packages: {'[+]': ['boldsymbol']}}
    };

Alternatively, use `\require{boldsymbol}` in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
