brainconn.reference.makeringlatticeCIJ

makeringlatticeCIJ(n, k)[source]

This function generates a directed lattice network with toroidal boundary counditions (i.e. with ring-like “wrapping around”).

Parameters:
  • N (int) – number of vertices
  • K (int) – number of edges
Returns:

CIJ – connection matrix
Return type:

NxN numpy.ndarray

Notes

The lattice is made by placing connections as close as possible to the main diagonal, with wrapping around. No connections are made on the main diagonal. In/Outdegree is kept approx. constant at K/N.
