what's the rank function used in make_local_connectivity_scorr.py

[DasDominus]

eg. in
def indx_3dto1d(idx, sz):
if (rank(idx) == 1):
idx1 = idx[0] * prod(sz[1:3]) + idx[1] * sz[2] + idx[2]
else:
idx1 = idx[:, 0] * prod(sz[1:3]) + idx[:, 1] * sz[2] + idx[:, 2]
return idx1

what's the rank method used?

To anyone who might stumble upon this:

The rank here is calculating the matrix rank, which post python3 & numpy version (can't recall which one)
is calculated with:

numpy.linalg.matrix_rank
