Procedure GMP::Column::SetType(GMP, column, type)

# GMP::Column::SetType¶

The procedure GMP::Column::SetType changes the type of a column in the matrix of a generated mathematical program.

GMP::Column::SetType(
GMP,            ! (input) a generated mathematical program
column,         ! (input) a scalar reference or column number
type            ! (input) an element in AllColumnTypes
)


## 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.

type

An element in AllColumnTypes.

## Return Value¶

The procedure returns 1 on success, or 0 otherwise.

Note

Use GMP::Column::SetTypeMulti if the type of many columns corresponding to some variable have to be set, because that will be more efficient.
