<dd>
<p>Convert to upper case.
</p>
<p>Converts all the characters in all the strings in <var class="var">obj</var> to upper case.
</p>
<p>This currently delegates to Octave’s own <code class="code">upper()</code> function to
do the conversion, so whatever character class handling it has, this
has.
</p>
<p>Returns a string array of the same size as <var class="var">obj</var>.
