Inheritance diagram for Set:
Abstract

GAMS Set.

Represents a GAMS Set.

Example:

c = Container();
s1 = symbol.Set.construct(c, 's1');
s2 = symbol.Set.construct(c, 's2', {s1, '*', '*'});
s3 = symbol.Set.construct(c, 's3', '*', 'records', {'e1', 'e2', 'e3'}, 'description', 'set s3');
matlab::gams::transfer::Container
GAMS Transfer Container stores (multiple) symbols.

Member Function Documentation

◆ construct()

static function construct ( in  varargin)
static

Constructs a GAMS Set.

Required Arguments:

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

Optional Arguments:

  1. domain (cellstr or Set): List of domains given either as string or as reference to a symbol.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 = symbol.Set.construct(c, 's1');
s2 = symbol.Set.construct(c, 's2', {s1, '*', '*'});
s3 = symbol.Set.construct(c, 's3', '*', 'records', {'e1', 'e2', 'e3'}, 'description', 'set s3');

◆ 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:

  1. destination (Container): Destination Container

Optional Arguments:

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

◆ describe()

static function describe ( in  symbols)
static

Returns an overview over all sets given.

See Symbol Overview for more information.

Required Arguments:

  1. symbols (list): List of sets to include.

The overview is in form of a table listing for each symbol its main characteristics and some statistics.
