6 Data Containers

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.
