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.
\left
and\right
should be outside the arrays, not inside. where they are now, each is in a different cell, so it would need to be matched within the same cell. i don't think that's what you want.\left[
