符号放大

Question

我怎样才能编写代码来增加每个符号而不删除现有的包？

例如我可以编写以下代码来放大“小”符号：

\makeatletter
\mathchardef\standardless=\mathcode`<
\DeclareRobustCommand{\tauyecoless}{
  \mathbin{\mathpalette\tauyeco@less\relax}
}
\newcommand{\tauyeco@less}[2]{
  \raisebox{-0.03\height}{\scalebox{1.35}{\hspace{-0.1mm}$\m@th#1\standardless$}}
}
\begingroup\lccode`~=`< \lowercase{\endgroup\let~}\tauyecoless
\AtBeginDocument{\mathcode`<="8000 }
\makeatother

我想用其他符号写这个代码

我的代码：

\documentclass[a5paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{refcount}
\usepackage{helvet}
\renewcommand\familydefault{\sfdefault}
\usepackage{mathastext}
\usepackage{MnSymbol}

\begin{document}

\[\neq,\leq,\geq,\Rightarrow,\times,\circ,\cup,\cap,\subset,\supset,\in,\equiv\]

\end{document}

Answer 1

我认为您只是想放大符号。您可以通过重新声明字体形状并引入放大系数来实现。

\documentclass[a5paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{refcount}
\usepackage{helvet}
\renewcommand\familydefault{\sfdefault}
\usepackage{mathastext}
\usepackage{MnSymbol}
\usepackage{graphicx}
