MATRIX_VAR column1 <,column2,...> ;

The DATA_MATRIX_VAR statement enables you to explicitly define the data set variable names for PROC OPTNET to use when it reads the data set that is specified in the DATA_MATRIX= option in the PROC OPTNET statement. The format of the matrix input data set is defined in the section Matrix Input Data. The value of each column variable must be numeric.
