5. Strings

A string constant consists of a sequence of characters enclosed in either double-quote or single-quote marks. For example, both of the following expressions

"parrot"
'parrot'

represent the string whose contents are ‘parrot’. Strings in Octave can be of any length.

Since the single-quote mark is also used for the transpose operator (see section Arithmetic Operators) but double-quote marks have no other purpose in Octave, it is best to use double-quote marks to denote strings.

Strings can be concatenated using the notation for defining matrices. For example, the expression

[ "foo" , "bar" , "baz" ]

produces the string whose contents are ‘foobarbaz’. See section Numeric Data Types, for more information about creating matrices.
