Math & Science ⇒ Matrix Equation Number

[mppxtylr]

Hi there,

I have the following matrix:

Code: Select all

\begin{displaymath}
	\begin{bmatrix}
		V_a \\
		V_b \\
		V_c 
	\end{bmatrix}=\begin{bmatrix}
		1 & 1 & 1 \\
		1 & a^2 & a  \\
		1 & a & a^2
	\end{bmatrix}
	\begin{bmatrix}
		V_{a0} \\
		V_{b0} \\
		V_{c0}
	\end{bmatrix}\,
\label{eq:symmetrical}
\end{displaymath}

Is there a way to give it an equation number that shows to the right in brackets, eg. (1)

Thanks in advance!

With

Code: Select all

\numberwithin{equation}{section}

or correspondingly

Code: Select all

\numberwithin{equation}{section} %sets equation numbers <chapter>.<section>.<index>
\numberwithin{equation}{subsection} %sets equation numbers <chapter>.<section>.<subsection>.<index>
\numberwithin{equation}{subsubsection} %sets equation numbers <chapter>.<section>.<subsection>.<subsubsection>.<index>

Replace displaymath with equation to get numbered math formulas. Numbering will depend on the used document class.
