Private Member Functions
Default Compiler Generated Methods
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.
	SymScaledMatrix ()
	Default Constructor.
	SymScaledMatrix (const SymScaledMatrix &)
	Copy Constructor.
void	operator= (const SymScaledMatrix &)
	Overloaded Equals Operator.
Private Attributes
SmartPtr< const SymMatrix >	matrix_
	const version of the unscaled matrix
SmartPtr< SymMatrix >	nonconst_matrix_
	non-const version of the unscaled matrix
SmartPtr< const SymScaledMatrixSpace >	owner_space_
	Matrix space stored as a SymScaledMatrixSpace.

Detailed Description

Class for a Matrix in conjunction with its scaling factors for row and column scaling.

Operations on the matrix are performed using the scaled matrix. You can pull out the pointer to the unscaled matrix for unscaled calculations.

virtual void Ipopt::SymScaledMatrix::MultVectorImpl	(	Number	alpha,
		const Vector &	x,
		Number	beta,
		Vector &	y
	)			const `[protected, virtual]`

Method for determining if all stored numbers are valid (i.e., no Inf or Nan).

It is assumed here that the scaling factors are always valid numbers.

Implements Ipopt::Matrix.

virtual bool Ipopt::SymScaledMatrix::HasValidNumbersImpl ( ) const [protected, virtual]

Method for determining if all stored numbers are valid (i.e., no Inf or Nan).

It is assumed here that the scaling factors are always valid numbers.

Reimplemented from Ipopt::Matrix.
