Status: Closed

Priority: Minor

Resolution: Fixed

Affects Version/s: 2.7

Fix Version/s: DEV backlog, FRONTEND

Component/s: HTML Editor (Atto)

Labels:

Affected Branches:MOODLE_27_STABLE
Description
With Atto text editor and equation editor enabled (using MathJax filter)
Select the Equation editor Advanced tab, The matrix (last) button does not display properly and inserts:
\left \begin
{matrix} a_1 & a_2 \ a_3 & a_4 \end{matrix}\right
rather than:
\left \begin
{matrix} a_1 & a_2 \ \ a_3 & a_4 \end{matrix}\right
Needs to be fixed in the settings,php file where the \ \ denoting the matrix new line needs to be \\\\. Presumably an escaping issue.
Also, consider adding a few more useful default expressions.
