Member Function Documentation
◆ construct()
|
static |
Constructs a GAMS Parameter.
See Creating a Symbol for more information.
Required Arguments:
- container (
Container
): Container object this symbol should be stored in - name (
string
): Name of parameter
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: Parameter 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:
- See also
- Parameter, Container.addParameter
◆ 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 iftrue
. Default:false
.
◆ describe()
|
static |
Returns an overview over all parameters given.
See Symbol Overview for more information.
Required Arguments:
- symbols (list): List of parameters to include.
The overview is in form of a table listing for each symbol its main characteristics and some statistics.
◆ dropZeros()
function dropZeros | ( | in | obj | ) |
Drops zero values from records.
For table-like record formats rows are dropped if values are zero. For matrix-like records formats, nothing happens.
