Procedure GMP::Column::Add(GMP, column)


The procedure GMP::Column::Add adds a column to the matrix of a generated mathematical program.

     GMP,            ! (input) a generated mathematical program
     column          ! (input) a scalar reference



An element in AllGeneratedMathematicalPrograms.


A scalar reference to a column.

Return Value

The procedure returns 1 on success, or 0 otherwise.


  • Use GMP::Column::AddMulti if many columns corresponding to some variable have to be added, because that will be more efficient.

  • Coefficients for this column can be added to the matrix by using the procedure GMP::Coefficient::Set. After calling GMP::Column::Add the type and the lower and upper bound of the column are set according to the definition of the corresponding symbolic variable. By using the procedures GMP::Column::SetType, GMP::Column::SetLowerBound and GMP::Column::SetUpperBound the column type and the lower and upper bound can be changed.
