brainspace.mesh.mesh_elements.get_cell2point_connectivity

brainspace.mesh.mesh_elements.get_cell2point_connectivity(surf, mask=None, dtype=<class 'numpy.uint8'>)[source]

Get cell to point connectivity.

Parameters:
  • surf (vtkDataSet or BSDataSet) – Input surface.
  • mask (1D ndarray, optional) – Binary mask. If specified, only get points within the mask. Default is None.
  • dtype (dtype, optional) – Data type. Default is uint8.
Returns:

output (sparse matrix, shape (n_cells, n_points)) – The connectivity matrix. The (i,j) entry is 1 if the i-th cell uses the j-th point.
