AdditiveCoupling

class brainpy.dyn.AdditiveCoupling(coupling_var, var_to_output, conn_mat, delay_steps=None, initial_delay_data=None, name=None, mode=None)

Additive coupling.

This class simulates the model of:

coupling = g * delayed_coupling_var
target_var += coupling

Parameters:

• coupling_var (Variable) – The coupling variable, used for delay.

• var_to_output (Union[Variable, Sequence[Variable]]) – The target variables to output.

• conn_mat (TypeVar(ArrayType, Array, Variable, TrainVar, Array, ndarray)) – The connection matrix.

• delay_steps (Union[int, TypeVar(ArrayType, Array, Variable, TrainVar, Array, ndarray), Initializer, Callable, None]) – The matrix of delay time steps. Must be int.

• initial_delay_data (Union[Initializer, Callable, TypeVar(ArrayType, Array, Variable, TrainVar, Array, ndarray), float, int, bool]) – The initializer of the initial delay data.

• name (str) – The name of the model.

update()

The function to specify the updating rule.
