'[]' not correct about latex2mathml HOT 2 CLOSED

@Sun-ZhenXing

I found issues here while testing:

1. Your latex string are missing "\" in-between matrix rows.
2. Even MathJax cannot render it correctly. (see image below)
   
3. The correct string should be r"\left[\begin{matrix}1 & 0 & 0 & 0\\0 & 1 & 0 & 0\\0 & 0 & 1 & 0\\0 & 0 & 0 & 1\end{matrix}\right]"
4. latex2mathml can correctly generate the corresponding MathML as seen below:

<math xmlns="http://www.w3.org/1998/Math/MathML"><mrow><mrow><mo fence="true" form="prefix" stretchy="true">[</mo><mrow><mtable><mtr><mtd><mn>1</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd></mtr><mtr><mtd><mn>0</mn></mtd><mtd><mn>1</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd></mtr><mtr><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>1</mn></mtd><mtd><mn>0</mn></mtd></mtr><mtr><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>0</mn></mtd><mtd><mn>1</mn></mtd></mtr></mtable></mrow><mo fence="true" form="postfix" stretchy="true">]</mo></mrow></mrow></math>

Rendering

Trying to view it on MathJax viewer correctly renders it:

It is possible that you are missing the right styling for these:

1. <mo fence="true" form="prefix" stretchy="true">[</mo>
2. <mo fence="true" form="postfix" stretchy="true">]</mo>

Thank you for your help.
But, the string is this r"\left[\begin{matrix}1 & 0 & 0 & 0\0 & 1 & 0 & 0\0 & 0 & 1 & 0\0 & 0 & 0 & 1\end{matrix}\right]", and this was created by SymPy. When I type it into textbox, it was somehow converted to \. And the string which I tested is r"\left[\begin{matrix}1 & 0 & 0 & 0\0 & 1 & 0 & 0\0 & 0 & 1 & 0\0 & 0 & 0 & 1\end{matrix}\right]".
The problem is I need a big "[", not just a "[".
Then I find the problem is Word, not latex2mathml or SymPy.
