How do I get rid of the unwanted <br> whatevers in this matrix code please?

[math]\left( {\begin{array}{*{20}{c}}
{{a_{11}}} & {{a_{12}}} & {{a_{13}}} \\
{{a_{21}}} & {{a_{22}}} & {{a_{23}}} \\
{{a_{31}}} & {{a_{32}}} & {{a_{33}}} \\
\end{array}} \right)[/math]

 

 

I have left the brackets of the math / math tags so the code will show up.

math\left( {\begin{array}{*{20}{c}}
{{a_{11}}} & {{a_{12}}} & {{a_{13}}} \\
{{a_{21}}} & {{a_{22}}} & {{a_{23}}} \\
{{a_{31}}} & {{a_{32}}} & {{a_{33}}} \\
\end{array}} \right)/math

If I paste this code into Codecogs the matrix is correctly displayed.

[latex] \left( {\begin{array}{*{20}{c}} {{a_{11}}} & {{a_{12}}} & {{a_{13}}} \\ {{a_{21}}} & {{a_{22}}} & {{a_{23}}} \\ {{a_{31}}} & {{a_{32}}} & {{a_{33}}} \\ \end{array}} \right) [/latex]

You have to put all the latex code on one line. <br> is the HTML line break tag. Is kind of weird that it renders it though.

Well rearranging what I wrote doesn't seem to work so what exact amendmends do I need to the code please?

[math]{\begin{array}{*{20}{c}} {{a_{11}}} & {{a_{12}}} & {{a_{13}}} \\ {{a_{21}}} & {{a_{22}}} & {{a_{23}}} \\{{a_{31}}} & {{a_{32}}} & {{a_{33}}} \\ \end{array}}[/math]



[math]\left( {\begin{array}{*{20}{c}}{{a_{11}}} & {{a_{12}}} & {{a_{13}}} \\{{a_{21}}} & {{a_{22}}} & {{a_{23}}} \\{{a_{31}}} & {{a_{32}}} & {{a_{33}}} \\\end{array}} \right)[/math]



Finally got it to work.

Thanks a bunch endy +1

 

What a cack handed piece of duff programming.

A machine should do what it is told period.

 

 

 

 

A computer is a literal genie.

 

Looking at it, you can use the WordPress selection at the bottom and it'll show up correctly for here. Rather than say, copy from the upper textarea, which I suspect we're all in the habit of doing.

I have no idea what you mean.

 

 

The original matrix was generated in MathType and pasted in between math tags.

The <br> and anything else was added by the system without being asked or told.

The text you pasted had line breaks already in it. The forum simply translated those into HTML code and from there into LaTeX.

 

You have to put it all on a single line to get rid of them.

 

This is the Codecog's method I was talking about:

 

 

 

Programs only do what they are told to do, you just have to tell them exactly what you want.

Thank you endy, for the continued support and explanations, which are very helpful.

That (helpful) is the difference between humans and programs.

 

IMHO humans invented ergometrics as well as programming, but forgot to teach the former to the latter.
