When you open a matrix, it is displayed in a Matrix editor window (Opening matrices).
(1) Title bar
The title bar shows the numbers and names of Visum matrices by default. When you open several matrices, the number of matrices opened is displayed in the title bar. It further shows the file name of external matrices. You can change the number and name of a matrix (Showing and editing matrix attribute values).
(2) Menu bar
As soon as a Matrix editor window becomes active, an additional Matrix editor menu is shown. This menu item provides matrix-specific functions.
(3) Matrix values
Here the matrix values of one or several matrices opened are displayed. The values in the matrix diagonals are highlighted in yellow. The shortcut menu offers various editing options. You can change the matrix display using various options (Filtering and aggregating matrix data, changing the view and Basic settings for matrices). Alternatively, you can show and edit the matrices in lists (Opening matrices in the List view).
(4) Toolbars of the Matrix editor window
The toolbars allow you to call specific program functions.

No synchronization with other windows |
The Matrix editor window is not synchronized with other windows. |
|
|
Synchronization with other windows: Highlight |
OD pairs or main OD pairs marked in the matrix editor window are also marked in other windows and vice versa. The synchronization also works between multiple matrix editor windows. |
