|
|
* MathJax/extensions/TeX/noUndefined.js
|
|
*
|
|
* This causes undefined control sequences to be shown as their macro
|
|
* names rather than producing an error message. So $X_{\xxx}$ would
|
|
* display as an X with a subscript consiting of the text "\xxx".
|
|
*
|
|
* To configure this extension, use for example
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* TeX: {
|
|
* noUndefined: {
|
|
* attributes: {
|
|
* mathcolor: "red",
|
|
* mathbackground: "#FFEEEE",
|
|
* mathsize: "90%"
|
|
* }
|
|
* }
|
|
* }
|
|
* });
