Importing matrix values during execution of the procedure sequence

1.  On the toolbar, click the  Open 'Procedure sequence' window button.

The Procedure sequence window opens.

2.  To the procedure sequence, at the position of your choice, add the Open matrix procedure of the Matrices category (Setting up and starting the procedure sequence).

Element Description

Select matrix directly

From the list of all matrices, select the desired matrix by its number.

Select matrix by properties

Select a matrix by certain attributes and their values.

5.  Confirm with OK.

The selected matrix is listed in the Reference object(s) column.

6.  In the row of the added procedure, click in the Variant/file column.

The icon is displayed.

7.  Then click the symbol.

The Open matrix window opens.

8.  Select the desired file.

Note: You can also select matrices with an external data format, for example Emme (Emme import)

9.  Click the Open button.

The file name appears in the Variant/file column.

Tip: Alternatively, you can double-click the cell in the Variant/file column and manually enter the path and file name.

10.  Execute the procedure (Executing procedures in the procedure sequence).

To the matrix, values of the selected matrix file are assigned.

Note: The number of zones or stop areas and the zone numbers or stop area numbers in the imported matrix file do not have to be identical with those in the Visum matrix you selected. Arithmetic operations, however, are only performed on matrix values with identical OD pairs. If the matrices do not have identical OD pairs, the following applies:

  • If the matrix file does not contain an OD pair, the matrix value null is used.
  • Any OD pairs that are not in the Visum file, will not be taken into account.
