MATRIX Subcommand (RELIABILITY command)

MATRIX reads and writes IBM® SPSS® Statistics matrix data files.

• Either IN or OUT and the matrix file in parentheses are required. When both IN and OUT are used on the same RELIABILITY procedure, they can be specified on separate MATRIX subcommands or on the same subcommand.
• If both IN and OUT are used on the same RELIABILITY command and there are grouping variables in the matrix input file, these variables are treated as if they were split variables. Values of the grouping variables in the input matrix are passed on to the output matrix (see Split Files (RELIABILITY command)).

OUT ('savfile'|'dataset'). Write a matrix data file or dataset. Specify either a filename, a previously declared dataset name, or an asterisk, enclosed in parentheses. Filenames should be enclosed in quotes and are stored in the working directory unless a path is included as part of the file specification. If you specify an asterisk (*), the matrix data file replaces the active dataset. If you specify an asterisk or a dataset name, the file is not stored on disk unless you use SAVE or XSAVE.

IN ('savfile'|'dataset'). Read a matrix data file or dataset. Specify either a filename, dataset name created during the current session, or an asterisk enclosed in parentheses. An asterisk reads the matrix data from the active dataset. Filenames should be enclosed in quotes and are read from the working directory unless a path is included as part of the file specification.
