Subexpression
(name, owner, expr, device, dimensions=Dimension(), dtype=None, scalar=False)[source]¶ Bases:
brian2.core.variables.Variable
An object providing information about a named subexpression in a model. Most of the time
Variables.add_subexpression
should be used instead of instantiating this class directly.Parameters: name : str
The name of the subexpression.
dimensions :
Dimension
, optionalThe physical dimensions of the subexpression.
owner :
Group
The group to which the expression refers.
expr : str
The subexpression itself.
device :
Device
The device responsible for the memory access.
dtype :
dtype
, optionalThe dtype used for the expression. Defaults to core.default_float_dtype.
scalar: bool, optional :
Whether this is an expression only referring to scalar variables. Defaults to
False
