我有方程式，我想引用其中一些。另外，我只想对我引用的方程式进行编号。出于某种原因，当我使用\mathtoolsset{showonlyrefs=true}- 时，它不起作用，当我使用\eqref它时，它只引用部分而不是方程式。如果我删除\mathtoolsset{showonlyrefs=true}，那么所有方程式都会被编号，无论我是否引用它们。
例如，使用以下行\mathtoolsset{showonlyrefs=true}：
\documentclass[peerreview]{IEEEtran}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{url}
\usepackage{ifthen}
\usepackage{cite}
\usepackage[cmex10]{amsmath} % Use the [cmex10] option to ensure complicance
% with IEEE Xplore (see bare_conf.tex)
\usepackage{subcaption}
%% Please note that the amsthm package must not be loaded with
%% IEEEtran.cls because IEEEtran provides its own versions of
%% theorems. Also note that IEEEXplore does not accepts submissions
%% with hyperlinks, i.e., hyperref cannot be used.
\usepackage{cleveref}
\usepackage{graphicx}
\usepackage{amsmath }
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{amsfonts}
\usepackage{mathtools}
\usepackage{dsfont}
\mathtoolsset{showonlyrefs=true}
\interdisplaylinepenalty=2500 % As explained in bare_conf.tex
%%%%%%
% correct bad hyphenation here
\hyphenation{op-tical net-works semi-conduc-tor}
\renewcommand{\baselinestretch}{1.48} % use only for one column version
