brainconn.reference.randmio_dir

randmio_dir(R, itr)

This function randomizes a directed network, while preserving the in- and out-degree distributions. In weighted networks, the function preserves the out-strength but not the in-strength distributions.

Parameters:

• W (NxN numpy.ndarray) – directed binary/weighted connection matrix
• itr (int) – rewiring parameter. Each edge is rewired approximately itr times.

Returns:

• R (NxN numpy.ndarray) – randomized network
• eff (int) – number of actual rewirings carried out
