| Definition: | for a network containing n nodes and b branches and in which a reference direction is chosen for each branch, matrix of type n × b where the element aij is:
- 0 if branch j is not incident at node i
- 1 if branch j is pointing away from node i
- −1 if branch j is pointing towards node i
NOTE – The figure below gives a network and the corresponding branch-node incidence matrix.
