Laplacian Matrix
Creates the laplacian matrix of the given network. The table has for each
edge a row and for each node a column. The cell value is the weight of
the node for the given edge.
Dialog Options
- Sort matrix by node name
- The columns are sorted
by the node name
- Normalize matrix
-
The entry value is -1/(sqrt(deg(i)*deg(j)) for connected nodes instead
of -1.
- Maximum number of parallel proceses
-
Decrease the number of parallel processes in case of memory problems.
