This option prints the row and/or column totals either to the line printer (LPX) file or to an (ascii) data file with either a SATURN-based format or a CSV-based format.
In the SATURN-based output the row and column totals are formatted as per that required for a trip ends control file as specified in Section 10.7.5 for matrix Furnessing; i.e. a namelist record followed by 11111 (row totals) and 22222 (column totals) data sets.
CSV-formatted files contain one record per zone with options to include or not: (a) sequential row numbers, (b) zone names per row, (c) level numbers per row, (d) row totals and/or (e) column totals. In addition an extra header record may be included with titles for each column included. CSV output is probably preferable if the user wishes to “manipulate” the data, for example using a spreadsheet, as opposed to simply printing data or transferring it elsewhere within MX.
Various options include whether or not to print zone names or sequential numbers (see 10.2.2), the source of the matrix (internal or external ufm), whether or not zero values are included and whether (in the case of stacked matrices) whether row/column totals from a single level or from the full matrix are output.
A further option allows the sum of all elements in the matrix to be output as a single line to an ascii file, in which case the data line may be “appended” (i.e. added) to an existing file. The append option is useful, e.g., as part of a set of runs over several forecast years when it is desired to create a file for input to a spreadsheet containing matrix totals by forecast year.
Note that, in this case, data is output in the order Grand Totals / Intra-zonals / Inter-zonals which is different from that used under Section 10.11 – Totals / Inters / Intras. No particular reason – it just is!
Note that if the output file has the extension .CSV (the default) then the output format is automatically in CSV such that commas are added at the end of each numerical field.
