I am trying to enter a matrix into Lyx on multiple lines. I enter the matrix into lyx and then edited the code in TeX to get it as close as I want. The problem is I can't find a way to get the large brackets on either side. If I use bmatrix it give me the brackets on both lines, I want the brackets on extreme ends. This is what I have so far:

\begin{multline*}
B_{ij}=\begin{matrix} 0.000281 & 0.000103 & 0.000009\\
0.000103 & 0.000181 & 0.000004\\
0.000009 & 0.000004 & 0.000417 \\
 -0.00014 & -0.000015 & -0.00013\\
0.000002 & 0.000002 & -0.000153\\
0.000027 & 0.00003 & -0.000107 \end{matrix} \\
\begin{matrix} -0.00001 & -0.00001 & 0.000027 \\
 -0.000015 & 0.000002 & 0.00003\\
 -0.000131 & -0.000153 & -0.000107\\
0.000221 & 0.000094 & 0.00005\\
0.000094 & 0.000243 & 0\\
0.00005 & 0 & 0.000358\end{matrix}
\end{multline*}

I want it to look like this: enter image description here

    So your question is how to typeset a matrix with a bracket on one side and no bracket on the other side?

  • Why do you use multline here? equation is fine.

  • I am using the IEEEtran style document and I want it to fit the width of one column. Feb 15, 2017 at 17:20

Use a standard matrix as you have it now, then select the matrix and click the Insert delimiters button on the toolbar:

Heading

Uncheck Keep matched, and select the appropriate delimiters, i.e. a bracket on one side and (None) on the other.
