Connects two layers with identical blocked_representations that use strength_patterns. Equivalent to a special matrix of matrices, in which the diagonal matrices have diagonal structure and off-diagonal matrices are zero. Also equivalent to a blocked_connection of diag_connections. That is: Matching elements are connected with excitation; mismatching elements in the same block are connected with inhibtion; connections between elements of different blocks have zero connections.
