I want to assign an equation number to the following matrix equation; I want a number in brackets on the right side, after the equation.
\[
\begin{bmatrix}

2 \\
3 \\
\end{bmatrix}
\]
But adding \begin{equation} \end{equation}
around this throws an error at \[
. How can I number this matrix equation properly?
equation
instead of\[ \]
not in addition to it.
