Parameters

iis

Type:  SystemInt32
The ordinal number of the IIS to get data for.

p_nrows

Type:  SystemInt32
Pointer to an integer where the number of rows in the IIS will be returned.

p_ncols

Type:  SystemInt32
Pointer to an integer where the number of bounds in the IIS will be returned.

rowind

Type:  SystemInt32
Indices of rows in the IIS. Can be null if not required.

colind

Type:  SystemInt32
Indices of bounds (columns) in the IIS. Can be null if not required.

contype

Type:  SystemChar
Sense of rows in the IIS:

• L: for less or equal row;
• G: for greater or equal row.
• E: for an equality row (for a non LP IIS);
• 1: for a SOS1 row;
• 2: for a SOS2 row;
• W: for a piecewise linear constraint;
• X: for a general constraint;
• I: for an indicator row.

Can be null if not required.

bndtype

Type:  SystemChar
Sense of bound in the IIS:

• U: for upper bound;
• L: for lower bound.
• F: for fixed columns (for a non LP IIS);
• B: for a binary column;
• I: for an integer column;
• P: for a partial integer columns;
• S: for a semi-continuous column;
• R: for a semi-continuous integer column.

Can be null if not required.

duals

Type:  SystemDouble
The dual multipliers associated with the rows. Can be null if not required.

djs

Type:  SystemDouble
The dual multipliers (reduced costs) associated with the bounds. Can be null if not required.

isolationrows

Type:  SystemChar
The isolation status of the rows:

• -1: if isolation information is not available for row (run iis isolations);
• 0: if row is not in isolation;
• 1: if row is in isolation.

Can be null if not required.

isolationcols

Type:  SystemChar
The isolation status of the bounds:

• -1: if isolation information is not available for column (run iis isolations);
• 0: if column is not in isolation;
• 1: if column is in isolation.

Can be null if not required.
