I have an equation:
\begin{equation}
MMAV1 = \frac{1}{N} \sum_{n=1}^N \omega_n|x_n|, \\
\omega_n =
\begin{cases}
1 & if 0.25N \leq n \leq 0.75N \\
0.5 & otherwise \\
\end{cases}
\label{equ:MMAV1}
\end{equation}
and I want the cases to be displayed on the next line.
I have tried using \begin{align} but that splits it into two equations with two reference numbers.
Does somebody know how to do this?
Best Answer
You can use aligned instead of align environment
Of course, you can ommit the
\\
after\omega_n
, if you do not want only the cases to be in a different line.Also the split environment can do the trick (same use).
Both of the above need the
amsmath
package.
