\section{Introduction}


The package \texttt{plex-otf} supports all families with specific optional
arguments:




\begin{tabular}{@{} >{\ttfamily}l l l @{}}\\\toprule
\emph{name} & \emph{value} &\emph{meaning}\\\midrule
mono & true/false & use only the IBM Plex Mono\\
serif & true/false & use only the IBM Plex Serif\\
sans & true/false & use only the IBM Plex Sans\\
math & true/false & use the Plex Math \\
RM & code & options for IBM Plex Serif\\
SS & code &  options for IBM Plex Sans\\
SScon & code &  options for IBM Plex Sans Condensed\\
TT & code &  options for IBM Plex Mono\\
MM & code &  options for IBM Plex Math\\
%semibold & true/false & use SemiBold instead of Bold\\
RMSCfont  & font & font name for small caps\\
SSSCfont  & font & font name for small caps\\
DefaultFeatures & code &  for all font styles\\\bottomrule
\end{tabular}

we use instead:

\section{Examples with using Small Caps fonts}
As already mentioned, the Plex font family has no small caps. If you need one then you can define another
font for the small caps. If the font has to structure like the \TeX\ Gyre fonts:

\begin{verbatim}
texgyreheros-regular.otf
texgyreheros-bold.otf
texgyreheros-italic.otf
texgyreheros-bolditalic.otf
\end{verbatim}


then you have to define all combinations yourself 

\begin{verbatim}
\usepackage[SS={   SmallCapsFont = texgyreheros-regular,
     SmallCapsFeatures = {Letters=SmallCaps,Scale=MatchUppercase},
          BoldFeatures = { SmallCapsFont=texgyreheros-bold},
        ItalicFeatures = { SmallCapsFont=texgyreheros-italic},
     BoldItalicFeatures= { SmallCapsFont=texgyreheros-bolditalic}}]{plex-otf}
\end{verbatim}


%\clearpage

\end{externalDocument}



\section{Math examples}

There is only the regular version of the math font \cs{mathnormal}. The bold version is
faked by the option \texttt{FakeBold}:

\begin{verbatim}
  \setmathfont[\PlexMM@features,version=normal]{IBMPlexMath-Regular.otf}
  \setmathfont[\PlexMM@features,FakeBold=3,version=bold]{IBMPlexMath-Regular.otf}
\end{verbatim}



\begin{verbatim}
Here's some text. And here's some math:
\[ 
  \phi(x)=\int_{-\infty}^{x} e^{-x^{2}/2} 
\]
And now bold math:
\boldmath
\[ 
  \phi(x)=\int_{-\infty}^{x} e^{-x^{2}/2} 
\]
\unboldmath

$f(x)=13\int$ \boldmath$f(x)=13 \int$\unboldmath

Euro and copyright symbols are available: \texteuro\ \textcopyright.
