- Procedure MatrixUnfreezeColumn(MP, column)
MatrixUnfreezeColumn
The procedure MatrixUnfreezeColumn
frees a column that was fixed
with MatrixFreezeColumn
. After calling MatrixUnfreezeColumn
the
value of the column can vary again between its lower and upper bound.
MatrixUnfreezeColumn(
MP, ! (input) a mathematical program
column ! (input) a scalar value
)
Arguments
- MP
A mathematical program that was previously solved. The mathematical program should be a linear or mixed-integer linear programming model.
- column
A scalar reference to an existing fixed column in the matrix.
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.
