<p>Octave supports a wide range of functions for manipulating strings.
Since a string is just a matrix, simple manipulations can be accomplished
using standard operators. The following example shows how to replace
all blank characters with underscores.
</p>
<div class="example">
<div class="group"><pre class="example-preformatted">quote = ...
"First things first, but not necessarily in that order";
quote( quote == " " ) = "_"
⇒ quote =
First_things_first,_but_not_necessarily_in_that_order
</pre></div></div>
<p>For more complex manipulations, such as searching, replacing, and
general regular expressions, the following functions come with Octave.
