Incidence matrix import
Incidence matrix is a matrix structure used to model graphs. Incidence matrix column represents graph edges and rows graph nodes. Thus, if matrix has four columns, it also models a graph with four edges. If matrix has seven rows it models a graph with seven nodes. Thinking now single column, representing one edge. If column cell contains a value 1, the edge, column represents connects to the node the value represents. Compared to adjacency matrix, an incidence matrix can model edges with more than two nodes. Say this in terms of topic maps, incidence matrix can represent not only binary associations but n-ary associations in general.
Wandora's incidence matrix import feature starts with menu option File > Import > Incidence matrix import. Matrix cell values are separated with space characters and rows with new line character.
