The MATRIX command is used to specify that a matrix report is to be constructed. Matrix reports show how one set of encyclopedia entries correlates to a second set of definition entries in a spreadsheet-type layout.
The structure of this command is:
MATRIX value { level-command-statement level-command-statement level-command-statement }
The MATRIX command statement must conform to the following rules:
▪MATRIX, value (1, 2, 3, or 4), brackets (BEGIN and END or { and }), and level-command-statements must be separated by white space.
▪In multi-level reports, the order of the JOIN commands and level-command-statements must provide a clear path through the Entity and Relation Tables. For more information, see Relations between objects.
