network_laplacian_matrix

compas.datastructures.network_laplacian_matrix(network, normalize=False, rtype='array')

Construct a Laplacian matrix from a Network datastructure.

Parameters:

networkcompas.datastructures.Network

Network data structure.

normalizebool, optional

If True, normalize the entries such that the value on the diagonal is 1.

rtypeLiteral[‘array’, ‘csc’, ‘csr’, ‘coo’, ‘list’], optional

Format of the result.

Returns:

array_like

Constructed Laplacian matrix.

Notes

d = L.dot(xyz) is currently a vector that points from the centroid to the node. Therefore c = xyz - d. By changing the signs in the laplacian, the dsiplacement vectors could be used in a more natural way c = xyz + d.
