Detailed Description

Class for Matrices which are sum of symmetric matrices.

For each term in the sum we store the matrix and a factor.

Member Function Documentation

◆ SetTerm()

void Ipopt::SumSymMatrix::SetTerm ( Index  iterm,
Number  factor,
const SymMatrix matrix 
)

Method for setting term iterm for the sum.

Note that counting of terms starts at 0.

◆ GetTerm()

void Ipopt::SumSymMatrix::GetTerm ( Index  iterm,
Number factor,
SmartPtr< const SymMatrix > &  matrix 
) const

Method for getting term iterm for the sum.

Note that counting of terms starts at 0.

◆ NTerms()

Index Ipopt::SumSymMatrix::NTerms ( ) const

Return the number of terms.

◆ MultVectorImpl()

virtual void Ipopt::SumSymMatrix::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.

◆ HasValidNumbersImpl()

virtual bool Ipopt::SumSymMatrix::HasValidNumbersImpl ( ) const
protectedvirtual

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

A default implementation always returning true is provided, but if possible it should be implemented.

Reimplemented from Ipopt::Matrix.

◆ ComputeRowAMaxImpl()

virtual void Ipopt::SumSymMatrix::ComputeRowAMaxImpl ( Vector rows_norms,
bool  init 
) const
protectedvirtual

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

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

Implements Ipopt::Matrix.

◆ ComputeColAMaxImpl()

virtual void Ipopt::SumSymMatrix::ComputeColAMaxImpl ( Vector cols_norms,
bool  init 
) const
protectedvirtual

Implementation of ComputeColAMaxImpl, which calls ComputeRowAMaxImpl.

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

Reimplemented from Ipopt::SymMatrix.

◆ PrintImpl()

virtual void Ipopt::SumSymMatrix::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.

◆ operator=()

void Ipopt::SumSymMatrix::operator= ( const SumSymMatrix )
private

Default Assignment Operator.
