Subexpression class

(Shortest import: from brian2.core.variables import Subexpression)

class brian2.core.variables.Subexpression(name, unit, owner, expr, device, dtype=None, scalar=False)

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.

unit : Unit

The unit 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, optional

The 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

Attributes

device	The Device responsible for memory access
expr	The expression defining the subexpression
identifiers	The identifiers used in the expression
