class brainpy.connect.FixedPreNum(num, include_self=True, allow_multi_conn=False, seed=None, **kwargs)

Connect a fixed number pf pre-synaptic neurons for each post-synaptic neuron.

Parameters:

• num (float, int) – The conn probability (if “num” is float) or the fixed number of connectivity (if “num” is int).

• include_self (bool) – Whether create (i, i) conn ?

• seed (None, int) – Seed the random generator.

• allow_multi_conn (bool) –

  Allow one pre-synaptic neuron connects to multiple post-synaptic neurons?
