Public Attributes
int	numberOfRows
	Every cone has (at least) two dimensions; no distinction is made between vector cones and matrix cones.
int	numberOfColumns
int	numberOfOtherIndexes
	Multidimensional tensors can also form cones (the Kronecker product, for instance, can be thought of as a four-dimensional tensor).
int *	otherIndexes
int	coneType
	The type of the cone (one of the values in ENUM_CONE_TYPE).
int	idx
	cones are referenced by an (automatically created) index
std::string	semidefiniteness
	we need to distinguish positive and negative semidefiniteness
bool	isPositiveSemiDefinite
	information about semidefiniteness is also tracked in a boolean variable

Detailed Description

The in-memory representation of a cone of semidefinite matrices.

SemidefiniteCone::SemidefiniteCone ( )

The SemidefiniteCone class constructor.

Definition at line 1156 of file OSInstance.cpp.

SemidefiniteCone::~SemidefiniteCone ( )

The SemidefiniteCone class destructor.

Definition at line 1165 of file OSInstance.cpp.

std::string SemidefiniteCone::getConeName ( ) [virtual]

Reimplemented from Cone.

Definition at line 1172 of file OSInstance.cpp.

std::string SemidefiniteCone::getConeInXML ( ) [virtual]

Write a SemidefiniteCone object in XML format.

This is used by OSiLWriter to write a <cone> element.

Implements Cone.

Definition at line 7950 of file OSInstance.cpp.

bool SemidefiniteCone::IsEqual ( SemidefiniteCone * that )

A function to check for the equality of two objects.

Reimplemented from Cone.

Definition at line 8899 of file OSInstance.cpp.

bool SemidefiniteCone::setRandom	(	double	density,
		bool	conformant,
		int	iMin,
		int	iMax
	)

A function to make a random instance of this class.

Parameters:

	density,:	corresponds to the probability that a particular child element is created
	conformant,:	if true enforces side constraints not enforceable in the schema (e.g., agreement of "numberOfXXX" attributes and <XXX> children)
	iMin,:	lowest index value (inclusive) that a variable reference in this matrix can take
	iMax,:	greatest index value (inclusive) that a variable reference in this matrix can take
