Latex math: align at multiple places -- alignat
04 Oct 2022It is possible to align equations to multiple places in latex, using alignat. However, the answers I found are mostly example-based. However however, I got it to work (below). First: decide how many sections you want. The number of sections is the argument for alignat – {3} in this example. Then use a & to start the line, and && in between sections. You can label each line.
Here’s some relevant StackOverflow answers. First, Second.
Here’s a minimal working example, and the output, below the example.
Latex MWE:
documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{alignat}{3}
& A + B && = C && \label{eq:line1} \\
& D && = E + 1, && \; \; \forall D \ge 0 \label{eq:line2}
\end{alignat}
Refs: Eq.s \ref{eq:line1} and \ref{eq:line2}.
\end{document}
And the output is:
