randmio_dir_signed(R, itr)

This function randomizes a directed weighted network with positively and negatively signed connections, while preserving the positive and negative degree distributions. In weighted networks by default the function preserves the out-degree 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
