octave: Data Types
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. External Code Interface,
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.
