In mathematics, an incidence matrix is a logical matrix that shows the relationship between two classes of objects, usually called an incidence relation. If the first class is X and the second is Y, the matrix has one row for each element of X and one column for each element of Y. The entry in row x and column y is 1 if x and y are related (called incident in this context) and 0 if they are not. There are variations; see below. WebFeb 24, 2012 · The incidence matrix can be applied only to directed graph only. The number of entries in a row apart from zero tells us the number of branches linked to that node. …
