Overview
MATRIX DATA reads raw matrix materials and converts them to a matrix data file that can be read
by procedures that handle matrix materials. The data can include vector statistics such as means
and standard deviations as well as matrices.
MATRIX DATA is similar to a DATA LIST command: it defines variable names and their order
in a raw data file. However, MATRIX DATA can read only data that conform to the general
format of SPSS-format matrices.
Matrix Files
Like the matrix data files created by procedures, the file that MATRIX DATA creates contains
the following variables in the indicated order. If the variables are in a different order in the
raw data file, MATRIX DATA rearranges them in the working data file.
• Split-file variables. These optional variables define split files. There can be up to eight
split variables, and they must have numeric values. Split-file variables will appear in the
order in which they are specified on the SPLIT subcommand.
