I was trying to make this matrix delimited by brackets within another matrix. Here is what I've managed to do so far, but I'm not too sure if I'm using the right approach. I tried to use bmatrix
earlier too but to no avail:
\begin{align}
\frac{\epsilon_{1}}{12h^2_{1}}
\begin{array}{c}
\left[
12 \\ -1 \\ 0 \\ 0 \\ 0 \\ 0 \\ 0
\right.
\end{array}
\begin{array}{c c c c c c c}
\left[
-24 & 12 & 0 & 0 & 0 & 0 & 0 \\
16 & -30 & 16 & -1 & 0 & 0 & 0 \\
-1 & 16 & -30 & 16 & -1 & 0 & 0 \\
0 & -1 & 16 & -30 & 16 & -1 & 0 \\
0 & 0 & -1 & 16 & -30 & 16 & -1 \\
0 & 0 & -1 & & 16 & -30 & 16 \\
0 & 0 & 0 & 0 & 0 & 12 & -24 \\
\right]
\end{array}
\begin{array}{ c }
\left.
0 \\ 0 \\ 0 \\ 0 \\ 0 \\ -1 \\ 12
\right]
\end{array} \notag
\end{align}
Note: I'm also having problems with adding the descriptive curly braces at the bottom of the matrix. Would be grateful if someone could help me out with that.
Best Answer
You can use nested matrices:
The empty row (with some negative vertical spacing) ensures that the outer brackets are larger than the inner ones.
Don't use
align
for single line displays.
