• All SPSS procedures that handle matrix materials use the MATRIX subcommand. The
MATRIX subcommand specifies the file from which the input matrix is read and/or the file
to which the output matrix is written.
• Matrix materials can be read from an external file as long as a working data file has been
created. The working file does not have to be the matrix data file.
• The procedures that read matrix materials cannot read every type of SPSS matrix data file.
For example, REGRESSION cannot read a matrix data file written by NONPAR CORR.
Figure 5 lists the structure of a matrix file and Figure 6 shows the dictionary information for
the same file.
Variable Order. The following variable order is standard for all SPSS matrix data files:
1. Split variables, if any. In Figure 5, the split variable is SEX.
2. ROWTYPE_ variable. The values of the ROWTYPE_ variable describe the contents of the
matrix data file, such as MEAN, STDDEV, N, and CORR.
3. Factor or grouping variables, if any.
