<p>The <cite>isomath</cite> package provides tools for a mathematical style
that conforms to the International Standard ISO&nbsp;80000-2 and is
common in science and technology. It changes the default shape of
capital Greek letters to italic, sets up bold italic and
sans-serif bold italic math alphabets with Latin and Greek
characters, and defines macros for markup of vector, matrix and
tensor symbols.</p>

<p>The package <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/fixmath.html">fixmath</a> by Walter Schmidt defines Greek letters as symbols
of type <tt class="literal">\mathalpha</tt> and takes them from the <tt class="literal">letters</tt> symbol font in
<tt class="literal">\mathnormal</tt> (as opposed to <tt class="literal">operators</tt> in <tt class="literal">fontmath.ltx</tt>).</p>
<p><cite>fixmath</cite> also defines the <tt class="literal">\mathbold</tt> alphabet, setting it to <tt class="literal">cmm</tt>.
<cite>isomath</cite> overwrites this definition with a configurable value for
the font family.</p>

<p>Unfortunately, the number of math alphabets in one math version is
