Topological matrices. Incidence matrices2.2 Topological matrices
For an analytical description of electric circuit graphs and their storage in computer memory in a digital form it is more convenient to represent graphs in the form of topological matrices. There are incidence matrices (node matrices), loop matrices and graph section matrices.
2.2.1 Incidence matrices It is said that if the node The where
incident branches
two non – zero elements: “+1” and “-1” because each branch is incident to two nodes and directed from one of them to the other. The sum of all elements of each column and, consequently, the sum of all matrix Matrix
