Merge ratio matrix

Merge ratio matrix is used to view topic merges between topic map layers in Wandora. Wandora can contain several separate topic maps at a time. These topic maps are called as topic map layers. It is very common that some topics locate in more than one layer i.e. several layers include the topic. Merge ratio matrix is a matrix where each row and column represent one topic map layer in Wandora. If user has three topic map layers in Wandora, the merge ratio matrix contains three rows and three columns. Each matrix cell number is the ratio of merged topics and all topics in these layers. Thus, diagonal cell values are always 1 as row topic map is same as the column topic map, and topic maps merge completely.

Example

Wandora samples contains a project ArtofNoise.wpr which consists of three layers. Wandora user opens the project and selects menu option Layers > Statistics > Merge ratio matrix.... User chooses to not to count percentages.
