class brian2.core.functions.Function(pyfunc, sympy_func=None, arg_units=None, arg_names=None, return_unit=None, arg_types=None, return_type=None, stateless=True, auto_vectorise=False)[source]

Bases: object

An abstract specification of a function that can be used as part of model equations, etc.

Attributes

implementations Stores implementations for this function in a FunctionImplementationContainer

Methods

`__call__`(*args)	Call self as a function.
`is_locally_constant`(dt)	Return whether this function (if interpreted as a function of time) should be considered constant over a timestep.

Details

implementations: Stores implementations for this function in a FunctionImplementationContainer

__call__(*args)[source]: Call self as a function.

is_locally_constant(dt)[source]: Return whether this function (if interpreted as a function of time) should be considered constant over a timestep. This is most importantly used by TimedArray so that linear integration can be used. In its standard implementation, always returns False.
