Data structures of matrices in Visum-specific text formats
Generally, matrices in text format have the following data structure:
- First row: Format code, e.g. $V;D2
- $V, $O, $E, $S, $T for the matrix file format
- M, means of transport number for the part V format ($VM)
- D and the number of decimal places (if > 0)
Note: For the additional parameters D and M please refer to the examples below which illustrate the combination with the format $V (Format $V). |
- Header corresponds to the selected options, meaning with or without transport mode identifier (only in the part V format)
- From - To: assignment time period
- Data block
The data block is described below, with example matrices.
- $NAMES
List of numbers and names of the rows and columns
Comment lines
- Visum adds specific comments to the file, depending on the format (e.g. the total amount per origin or destination object).
- They are permitted in the header as well as in the data block.
- They must begin with *
- They are skipped by the program.
