Procedure MatrixModifyDirection(MP, direction)

MatrixModifyDirection

The procedure MatrixModifyDirection changes the direction of a mathematical program to 'maximize', 'minimize' or 'none'. The direction 'none' is the instruction to the solver to find a feasible solution. If the type of the mathematical program is 'MIP' then the solver will try to find an integer feasible solution.

MatrixModifyDirection(
     MP,             ! (input) a mathematical program
     direction       ! (input) a direction
     )

Arguments

MP

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

direction

One of the directions 'maximize', 'minimize' or 'none'.

Return Value

The procedure returns 1 on success, or 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.
