Export incidence matrix
Wandora's Export Incidence Matrix feature takes a topic map or a collection of associations, or topics, and exports an incidence matrix. Incidence matrix columns represents associations and rows topics. If matrix cell contains number 1 (one) then row topic plays a role in the column association. If matrix cell contains number 0 (zero) then topic plays no role in the column association. If column association is binary, the sum of row numbers is 2 (two). Matrix doesn't contain association type nor roles. Also, matrix contains no other information about topic except their appearance in associations. Incidence matrix export feature is very lossy.
Wandora's Export Incidence Matrix feature starts with menu option File > Export > Export aincidence matrix... or in context of topics with menu option Topics > Export > Export incidence matrix..., or in context of topic map layer with menu option Export layer > Export incidence matrix.... First option exports all topics in Wandora application. Second option exports only selected topics, and third option only selected topic map layer.
