\section*{Test the isomath Package}

% Print font package, isomath options, and resulting font families::

Fontpackage: [\fontpackageoptions]\{\fontpackage\}\\
Isomath called with options: [\isomathoptions]\\
Default font families:
\makeatletter
\begin{tabular}[t]{rlrl}
 serif & \texttt{\rmdefault} &
   sans-serif & \texttt{\sfdefault}\\
 isomath-serif & \texttt{\isomath@rmdefault} &
   isomath-sf & \texttt{\isomath@sfdefault}\\
\end{tabular}

\subsection*{Math alphabets}

If there are other symbols in place of Greek letters in a math
alphabet, it uses T1 or OT1 font encoding instead of OML.

% A teststring with Latin and Greek letters::

\newcommand{\teststring}{%
% capital Latin letters
A,B,C,
% capital Greek letters
\Gamma,\Delta,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,
% small Greek letters
\alpha,\beta,\pi,\nu,\omega,
% small Latin letters:
% compare \nu, \omega, v, and w
v,w,
% is there a true italic form of a and g?
a,g,
}

\begin{eqnarray*}
\mbox{mathnormal} &  & \teststring \\
\mbox{mathit} &  & \mathit{\teststring}\\
\mbox{mathrm} &  & \mathrm{\teststring}\\
\mbox{mathbf} &  & \mathbf{\teststring}\\
\mbox{mathsf} &  & \mathsf{\teststring}\\
\mbox{mathtt} &  & \mathtt{\teststring}
\end{eqnarray*}
 New alphabets bold-italic, sans-serif-italic, and sans-serif-bold-italic.
\begin{eqnarray*}
\mbox{mathbold}     &  & \mathbold{\teststring}\\
\mbox{mathsans}     &  & \mathsans{\teststring}\\
\mbox{mathboldsans} &  & \mathboldsans{\teststring}
\end{eqnarray*}
%
Do the math alphabets match?

$
\mathnormal  {a x \alpha \omega}
\mathbold    {a x \alpha \omega}
\mathboldsans{a x \alpha \omega}
\quad
\mathboldsans{T C \Theta \Gamma}
\mathbold    {T C \Theta \Gamma}
\mathnormal  {T C \Theta \Gamma}
$

\subsection*{Vector symbols}

Symbols for vectors are boldface italic:
$\vec{\lambda}=\vec{e}_{1}\cdot\vec{a}$.


\subsection*{Matrix symbols}

Symbols for matrices are boldface italic, too:%
\footnote{However, matrix symbols are usually capital letters whereas vectors
are small ones. Exceptions are physical Quantities like the force
vector $\vec{F}$ or the electrical field $\vec{E}$.%
}
$\matrixsym{\Lambda}=\matrixsym{E}\cdot\matrixsym{A}.$


\subsection*{Tensor symbols}

Symbols for tensors are sans-serif bold italic,

\[
   \tensorsym{\alpha}  =  \tensorsym{e}\cdot\tensorsym{a}
   \quad \Longleftrightarrow \quad
   \alpha_{ijl}  =  e_{ijk}\cdot a_{kl}.
\]


The permittivity tensor describes the coupling of electric field and
displacement: \[
\vec{D}=\epsilon_{0}\tensorsym{\epsilon}_{\mathrm{r}}\vec{E}\]
