Get \ref for equations working like \cite for contiguous references

Question

When referencing a list of equations like see Eq.12, 13, 14 and 15 the \cite command behaviour, which allows a single list of references, should be preferred I think. Is there something equivalent for the \ref command that would allow \ref{eq1,eq2,eq3}?

Answer 1

The \cref macro of the cleveref package is your friend.

\documentclass{article}

\usepackage{cleveref}

\begin{document}

\begin{equation}
\label{eq:a}
a^2 + b^2 = c^2
\end{equation}

\begin{equation}
\label{eq:b}
d^2 + e^2 = f^2
\end{equation}

\begin{equation}
\label{eq:c}
g^2 + h^2 = i^2
\end{equation}

See \cref{eq:a,eq:b,eq:c}.

\end{document}
