3 Data Types
************

All versions of Octave include a number of built-in data types,
including real and complex scalars and matrices, character strings, a
data structure type, and an array that can contain all data types.

   It is also possible to define new specialized data types by writing a
small amount of C++ code.  On some systems, new data types can be loaded
dynamically while Octave is running, so it is not necessary to recompile
all of Octave just to add a new type.  Note: External Code Interface,
for more information about Octave’s dynamic linking capabilities.  Note:
User-defined Data Types describes what you must do to define a new
data type for Octave.

 -- : typeinfo ()
 -- : typeinfo (EXPR)

     Return the type of the expression EXPR, as a string.

     If EXPR is omitted, return a cell array of strings containing all
     the currently installed data types.
