MATRIX TO VARIABLE

MATRIX TO VARIABLE

LET Subcommand

Convert a matrix to a variable.

There may be times when it is desirable to convert a matrix to a variable. This command provides a simple and convenient method for converting a matrix to a variable.

LET <y> = MATRIX TO VARIABLE <m>
                  <SUBSET/EXPCEPT/FOR qualification>
where <m> is the previously created matrix;
            <y> is the resulting response variable;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET Y = MATRIX TO VARIABLE M

By default, the variable is created in column order from the matrix. That is, column 1 of the matrix is extracted, then column 2 of the matrix, and so on. To create the variable in row order, enter the command
SET MATRIX TO VARIABLE ROW

To restore column order, enter

SET MATRIX TO VARIABLE COLUMN

It is also sometimes desirable to convert a variable to a matrix. This can be done with the command
LET M = VARIABLE TO MATRIX Y

where Y is a previously created variable.
