<h2 class="chapter">5 Strings</h2>
<p><a name="index-strings-279"></a><a name="index-character-strings-280"></a><a name="index-g_t_0022-281"></a><a name="index-g_t_0027-282"></a>
A <dfn>string constant</dfn> consists of a sequence of characters enclosed in
either double-quote or single-quote marks. For example, both of the
following expressions
<pre class="example"> "parrot"
'parrot'
</pre>
<p class="noindent">represent the string whose contents are ‘<samp><span class="samp">parrot</span></samp>’. Strings in
Octave can be of any length.
<p>Since the single-quote mark is also used for the transpose operator
(see <a href="Arithmetic-Ops.html#Arithmetic-Ops">Arithmetic Ops</a>) but double-quote marks have no other purpose in Octave,
it is best to use double-quote marks to denote strings.
<p>Strings can be concatenated using the notation for defining matrices. For
example, the expression
<pre class="example"> [ "foo" , "bar" , "baz" ]
</pre>
<p class="noindent">produces the string whose contents are ‘<samp><span class="samp">foobarbaz</span></samp>’. See <a href="Numeric-Data-Types.html#Numeric-Data-Types">Numeric Data Types</a>, for more information about creating matrices.
