calculate_laplacian
Computes the Laplacian spectrum of a brain graph from an atlas, with the second eigenvalue indicating algebraic connectivity. Accepts optional weight threshold and connection type.
Instructions
Espectro del Laplaciano del grafo real de un atlas (autovalores,
ascendente): el segundo autovalor, en un grafo conexo, es su
"conectividad algebraica" -- cuánto le cuesta desconectarse.
connection_type nunca mezcla structural/functional/effective
(sección 8); min_weight es un umbral explícito que decide quien
llama, no uno aplicado de antemano al cargar los datos.
