Least-squares node positions for directed ENA.
Arguments
- line_weights
Numeric matrix (units x connections)
- points
Numeric matrix of rotated points (units x dims)
- numDims
Number of dimensions
- self_weight
Weight of a self-connection (the diagonal: ground i -> response i) in its code's node weight: 2 (default) counts it in both the node's row and column sums (Zhiqiang Cai's 2021 in + out rule); 1 counts it once.
