brainconn.similarity.corr_flat_und

corr_flat_und(a1, a2)

Returns the correlation coefficient between two flattened adjacency matrices. Only the upper triangular part is used to avoid double counting undirected matrices. Similarity metric for weighted matrices.

Parameters:

• A1 (NxN numpy.ndarray) – undirected matrix 1
• A2 (NxN numpy.ndarray) – undirected matrix 2

Returns:

r – Correlation coefficient describing edgewise similarity of a1 and a2

Return type:

float
