Inheritance diagram for Set:

GAMS Set.

Example:

c = Container();
s1 = Set(c, 's1');
s2 = Set(c, 's2', {s1, '*', '*'});
s3 = Set(c, 's3', '*', 'records', {'e1', 'e2', 'e3'}, 'description', 'set s3');

Constructor & Destructor Documentation

◆ Set()

function Set	(	in	container,
		in	name,
		in	varargin
	)

Constructs a GAMS Set.

See Creating a Symbol for more information.

Required Arguments:

container (Container): Container object this symbol should be stored in
name (string): Name of set

Optional Arguments:

domain (cellstr or Set): List of domains given either as string or as reference to a Set object. Default is {"*"} (for 1-dim with universe domain).

Parameter Arguments:

records: Set records, e.g. a list of strings. Default is [].
description (string): Description of symbol. Default is "".
is_singleton (logical): Indicates if set is a is_singleton set (true) or not (false). Default is false.
domain_forwarding (logical): If true, domain entries in records will recursively be added to the domains in case they are not present in the domains already. With a logical vector domain forwarding can be enabled/disabled independently for each domain. Default: false.

Example:

c = Container();
s1 = Set(c, 's1');
s2 = Set(c, 's2', {s1, '*', '*'});
s3 = Set(c, 's3', '*', 'records', {'e1', 'e2', 'e3'}, 'description', 'set s3');

Member Function Documentation

◆ copy()

function copy	(	in	obj,
		in	varargin
	)

Copies symbol to destination container.

Symbol domains are downgraded to relaxed if the destination container does not have equivalent domain sets, see also Symbol Domain.

Required Arguments:

destination (Container): Destination Container

Optional Arguments:

overwrite (bool): Overwrites symbol with same name in destination if true. Default: false.

◆ equals()

function equals	(	in	obj,
		in	symbol
	)

Checks equivalence with other symbol.

Note: A symbol is always linked to a container. This method does not check equivalence of the linked containers.

Required Arguments:

symbol (any): Other symbol
