LengthDelay#
- class brainpy.math.LengthDelay(delay_target, delay_len, initial_delay_data=None, name=None, batch_axis=None, update_method='rotation')[source]#
Delay variable which has a fixed delay length.
- Parameters:
delay_target (int, sequence of int) – The initial delay data.
delay_len (int) – The maximum delay length.
initial_delay_data (Any) –
The delay data. It can be a Python number, like float, int, boolean values. It can also be arrays. Or a callable function or instance of
Connector
. Note thatinitial_delay_data
should be arranged as the following way:delay = 1 [ data delay = 2 data ... .... ... .... delay = delay_len-1 data delay = delay_len data ]
Changed in version 2.2.3.2: The data in the previous version of
LengthDelay
is:delay = delay_len [ data delay = delay_len-1 data ... .... ... .... delay = 2 data delay = 1 data ]
- name: str
The delay object name.
- batch_axis: int
The batch axis. If not provided, it will be inferred from the delay_target.
- update_method: str
The method used for updating delay.
