You can follow the example below yourself using the Demo2.gpn file.
In the upper section of the window you can set which master data elements you wish to display in the lines, columns and the individual cells.

The figure on the next page displays the lesson matrix from the Demo2.gpn file. The lines indicate the subject, the columns the classes and in the cells you can find the teacher and the weekly periods. In this way it is possible to recognise at a glance that teacher Hugo has two periods of “GEc” with classes 1a, 1b, 2b and 3a.
Clicking on a cell in the matrix displays the corresponding lesson in the details window at the bottom of the screen.

Changes can be made to the subject allocation in the display window of the lesson matrix.
Couplings are highlighted in the lesson matrix; all those cells with elements of the coupling lesson are displayed with a blue border, as you can see in the figure with the example of teacher Hugo’s geography lesson.
Kopplungen können auch - wie beim Stundenplan - mit einem Punkt gekennzeichnet werden. Klicken Sie dazu in der Matrix auf die Schaltfläche <Einstellungen> und setzen Sie bei „Kopplung markieren“ ein Häkchen.
Several units form one lesson
The lesson list (“L-No./Per”) in the upper part of the window displays the lesson number followed by the number of periods for a selected cell. If there are several entries here this means that the lesson is divided into several units. In the current example this would be the case for teacher Hugo’s German lesson in class 4. Four of the six periods are part of lesson number 61 while the remaining two are part of lesson 72.
By clicking on the relevant line in the lesson list you will see in the details window that teacher Hugo takes lesson 61 on his own while a coupling with English exists for lesson 72 with teacher Cervantes.

Filter
By marking one of the filter selection fields you can limit the entries in the matrix to those elements that interest you. For example, in the figure below the filter was set for the subject “HI” (the subjects are displayed in the lines). This results in only those columns being displayed where the cell for subject “HI” is not empty. This means that only those teachers are displayed who actually teach history.

This function can of course be used in the same way for column elements. When filtering the cells, the display is reduced to just those rows containing the relevant element.
