◆ construct()
|
static |
Constructs a GAMS Equation.
See Creating a Symbol for more information.
Required Arguments:
- container (
Container
): Container object this symbol should be stored in - name (
string
): Name of equation - type (
string
,int
or EquationType): Specifies the variable type, either asstring
, asinteger
given by any of the constants in EquationType or EquationType.
Optional Arguments:
- domain (
cellstr
orSet
): List of domains given either asstring
or as reference to a symbol.Set object. Default is{}
(for scalar).
Parameter Arguments:
- records: Equation records. Default is
[]
. - description (
string
): Description of symbol. Default is""
. - domain_forwarding (
logical
): Iftrue
, 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();
e2 = symbol.Equation.construct(c, 'e2', 'l', {'*', '*'});
