1. Overview The autonum package (found at autonum.info ) provides a sophisticated solution for managing equation numbering in LaTeX documents. Its core purpose is to automatically control which equations receive numbers based on whether they are referenced elsewhere in the text. autonum.info

autonum is often preferred over mathtools ’ showonlyrefs because autonum works with more environments and handles \label placement more robustly. \documentclassarticle \usepackageamsmath \usepackage[colorlinks]hyperref \usepackagecleveref \usepackageautonum \begindocument
