RELIABILITY can read a matrix data file created by a previous RELIABILITY command or by another procedure.
The matrix input file must have records of type N, MEAN, STDDEV, and
CORR for each split-file group. For more information, see the Universals
section.
Variable names, variable and value labels, and print
and write formats are read from the dictionary of the matrix data
file.
MATRIX=IN cannot
be used unless an active dataset has already been defined. To read
an existing matrix data file at the beginning of a session, use GET to retrieve the matrix file and then
specify IN(*) on MATRIX.
