<h2 class="chapter">6 Data Containers</h2>
<a name="index-containers"></a>
<p>Octave includes support for three different mechanisms to contain arbitrary
data types in the same variable: Structures, which are C-like, and are indexed
with named fields; containers.Map objects, which store data in key/value pairs;
and cell arrays, where each element of the array can have a different data type
and or shape. Multiple input arguments and return values of functions are
organized as another data container, the comma separated list.
