An Octave module can either load its symbols into the global namespace, so that they can be accessed directly without having to type the module name.
Alternatively, an Octave module can be accessed through a local variable, without being loaded globally.

To load an Octave module globally, simply type its name:

<p>
To access an Octave module through a local variable, without loading it globally, simply assign the module name (e.g. "example") to the desired local variable:
</p>
<div class="targetlang"><pre>
octave:1&gt; example = example;
octave:2&gt; example.gcd(6,9)
ans = 3
octave:3&gt; example.cvar.Foo
ans = 3
</pre></div>
<p>
The variable may have the same name as the module, or a shorter one:
</p>
<div class="targetlang"><pre>
octave:1&gt; ex = example;
octave:2&gt; ex.gcd(6,9)
ans = 3
octave:3&gt; ex.cvar.Foo
ans = 3
</pre></div>
<p>
It is also possible to rename the global variables namespaces with an assignment, as in:
</p>
<div class="targetlang"><pre>
octave:1&gt; example;
octave:2&gt; cvar.gcd(10,4)
ans = 2
octave:3&gt; some_vars = cvar;
octave:4&gt; some_vars.Foo
ans = 3
</pre></div>
<p>
Modules can also be loaded from within functions, even before being loaded in the base context.
If the module is also used in the base context, however, it must first be loaded again:
