In order to control equations numbering I use the Align*
environment where I put \numberthis
at the end of the equation that I want to number. After, I label the numbered equation but when I want to make a reference to that equation using \cref
command of the cleveref
package I obtain a wrong reference (to another page).
It is working with the minimal working example below, but it is not working in my thesis document (the reference send me to a figure in the page before the equation). Could some one say to me if there is something wrong ?
\documentclass[12pt,a4paper,english,french]{book}
\usepackage{amsmath}
\newcommand\numberthis{\addtocounter{equation}{1}\tag{\theequation}} % for numbering in the align* environment
\usepackage[colorlinks=true, linkcolor=blue]{hyperref}
\usepackage[nameinlink]{cleveref}
\begin{document}
Text
\begin{align*}
a & = b \numberthis \label{eqn413} \\
c & = d \\
e & = f \\
\end{align*}
\newpage
The \cref{eqn413} show that bla bla.
\end{document}
Best Answer
You should use
\refstepcounter{equation}
to get links correctly:Further, it may be better label like
\label{eq:<some name you will easily remember>}
instead of numbers.eq
says that it is an equation label and the name is unique to that equation. Please refer to: this Q and its answers.
