Procedure MatrixModifyLowerBound(MP, row, value)

MatrixModifyLowerBound

The procedure MatrixModifyLowerBound changes the lower bound of a column in the matrix.

MatrixModifyLowerBound(
     MP,             ! (input) a mathematical program
     column,         ! (input) a scalar value
     value           ! (input) a numerical expression
     )

Arguments

MP

A mathematical program that was previously solved. The mathematical program should be a linear or mixed-integer linear programming model.

row

A scalar reference to an existing column in the matrix.

value

The new value that should be assigned to the lower bound of the column.

Return Value

The procedure returns 1 on success, and 0 otherwise.

Note

As of AIMMS release 3.5, the matrix manipulation procedures have become deprecated. New projects should use the GMP library instead. Please refer to Table 5 for a mapping of the matrix manipulation procedures to corresponding GMP procedures.
