Function GMP::Column::GetStatus(GMP, column)

# GMP::Column::GetStatus

The function GMP::Column::GetStatus returns the status of a column in a generated mathematical program.

GMP::Column::GetStatus(
GMP,            ! (input) a generated mathematical program
column          ! (input) a scalar reference or column number
)


## Arguments

GMP

An element in AllGeneratedMathematicalPrograms.

column

A scalar reference to an existing column in the matrix or the number of that column in the range $$\{ 0 .. n-1 \}$$ where $$n$$ is the number of columns in the matrix.

## Return Value

An element in the predefined set AllRowColumnStatuses. The set AllRowColumnStatuses contains the following elements:

• Active,

• Deactivated,

• Deleted,

• NotGenerated,

• PresolveDeleted.

Note

• This function will return ‘PresolveDeleted‘ only if the generated mathematical program has been created with GMP::Instance::CreatePresolved. Status ‘PresolveDeleted‘ means that the column was generated for the original generated mathematical program but deleted when the presolved mathematical program was created.

• Status ‘Deactivated‘ is not possible for columns.
