|
|
* MathJax/extensions/TeX/enclose.js
|
|
*
|
|
* Implements the \enclose macros, which give access from TeX to the
|
|
* <menclose> tag in the MathML that underlies MathJax's internal format.
|
|
*
|
|
* Usage:
|
|
*
|
|
* \enclose{notation}{math} % enclose math using given notation
|
|
* \enclose{notation,notation,...}{math} % enclose with several notations
|
|
* \enclose{notation}[attributes]{math} % enclose with attributes
|
