Member Function Documentation

virtual void Ipopt::ZeroSymMatrix::MultVectorImpl	(	Number	alpha,
		const Vector &	x,
		Number	beta,
		Vector &	y
	)		const

protectedvirtual

Matrix-vector multiply.

Computes y = alpha * Matrix * x + beta * y

Implements Ipopt::Matrix.

virtual void Ipopt::ZeroSymMatrix::TransMultVectorImpl	(	Number	alpha,
		const Vector &	x,
		Number	beta,
		Vector &	y
	)		const

protectedvirtual

Since the matrix is symmetric, it is only necessary to implement the MultVectorImpl method in a class that inherits from this base class.

If the TransMultVectorImpl is called, this base class automatically calls MultVectorImpl instead.

Reimplemented from Ipopt::SymMatrix.

virtual void Ipopt::ZeroSymMatrix::ComputeRowAMaxImpl	(	Vector &	rows_norms,
		bool	init
	)		const

inlineprotectedvirtual

Compute the max-norm of the rows in the matrix.

The result is stored in rows_norms. The vector is assumed to be initialized.

Implements Ipopt::Matrix.

Definition at line 44 of file IpZeroSymMatrix.hpp.

virtual void Ipopt::ZeroSymMatrix::ComputeColAMaxImpl	(	Vector &	cols_norms,
		bool	init
	)		const

inlineprotectedvirtual

Since the matrix is symmetric, the row and column max norms are identical.

Reimplemented from Ipopt::SymMatrix.

Definition at line 47 of file IpZeroSymMatrix.hpp.

virtual void Ipopt::ZeroSymMatrix::PrintImpl	(	const Journalist &	jnlst,
		EJournalLevel	level,
		EJournalCategory	category,
		const std::string &	name,
		Index	indent,
		const std::string &	prefix
	)		const

protectedvirtual

Print detailed information about the matrix.

Implements Ipopt::Matrix.

void Ipopt::ZeroSymMatrix::operator= ( const ZeroSymMatrix & )

private

Overloaded Equals Operator.
