MATRIX DATA clears the active dataset and defines a new active dataset.
If CONTENTS is
not specified and ROWTYPE_ is not
specified on VARIABLES, MATRIX DATA assumes that the data contain
only CORR values and issues warning
messages to alert you to its assumptions.
With the default format, data values, including diagonal
values, must be in the lower triangle of the matrix. If MATRIX DATA encounters values in the upper
triangle, it ignores those values and issues a series of warnings.
With the default format, if any matrix rows span
records in the data file, MATRIX DATA cannot form the matrix properly.
MATRIX DATA does not allow format specifications for matrix materials. The procedure
assigns the formats shown in the following table. To change data formats,
execute MATRIX DATA and then
assign new formats with the FORMATS, PRINT FORMATS, or WRITE FORMATS command.
