include numeric, imaginary, characters, strings, logicals, and Other (NaN/Inf).
Other Literals
Inf and NaN are two special literals predefined in the OpenMatrix language.
Collections
A collection is an ordered grouping of elements (which may be literals or other collections).
Identifiers
Identifiers are user-defined names that can refer to literals, other identifiers, or functions.
Numerics
Numeric literals come in the form of a scalar, integer, decimal, or scientific notation (exponential).
Imaginary
Imaginary literals are numeric literals followed immediately by one of the characters that represents the imaginary constant i (defined as the square root of -1).
Strings
String literals are specified by a sequence of characters between ' (single quote) characters.
